HEAT RETENTIVE PLATES

HotSmart Plates are the ONLY patented HEAT RETENTIVE PLATES on the market; they use the Stefan-Boltzmann principle and patented technology What does this mean? The sketch below helps explain everything.
See also HotSmartUSA.com  
For how to manufacture HotSmarts you need to see previous posts. Patents are public domain (License required for the USA).






  • HotSmart Plates use a core of a specially developed -proprietary- microwave absorbing material
  • This core is enclosed in a cavity in the plate
  • The upper and lower components are basically transparent to microwave radiation
  • The core gets very hot and radiates in the infrared range of frequencies (heat)
  • The Stefan-Boltzmann law regulates this radiation
  • Both Microwaves and infrared radiation are electromagnetic radiation (Only different wave length)
  • HotSmart Plates need only ONE minute microwaving (1200W) and stay hot for over 30+ minutes  (over half hour) Believe it or not!
  • There is a big difference between a simple thick, heavy plate and a HotSmart Heat Retentive Plate.

CERAMIC PLATES WITH HEATERS INTEGRATED BY HOTSMART

A ceramic plate with a heater inside to keep food hot

Click the link above to see all about it!
 It looks like a regular plate but it has a heater inside...

A HotSmart used for a simple breakfast at home; it makes a big difference!
(The HotSmart Mug keeps coffee hot to the last sip)

By the way, the mug also has an integrated heater; the plates are excellent for steak, even better than skillets on a wooden base

Yes, from eggs over easy to steak and pasta and Chinese food
and... You name it!

As the US heads toward the Thanksgiving holiday, it seems appropriate to explore ways to keep our food warmer, longer. After all, the traditional Thanksgiving feast of turkey and all the trimmings has become the centerpiece of the day for many. (Along with, in many households, football.)

Enter Juan J. Ramirez. A former industrial engineer, Ramirez invented and patented a unique stay-hot dinnerware technology after losing his long-time job and suffering some health issues. “The idea came after I suffered a stroke and brain tumor surgery,” he explains in an email. “Well, the idea did not come because of the stroke, but because I lost my career of many years in manufacturing and I found myself unemployed and with lots of time available.”

Ramirez used that time to develop a line of dinnerware that, after only a minute in the microwave oven, will keep food in the center of the plate hot for more than 30 minutes. The rim of the plate, meanwhile, remains cool to the touch to minimize the chance of accidental burns.

Ramirez says HotSmart plates can be made using practically any ceramic material, from whiteware to bone china, and that “anybody making plates” would know the details of firing time and temperature. The trick is in the plates’ core of susceptor material, which absorbs microwave radiation and then releases the heat in a controlled manner. “It was about time the ceramic plate learned a few new tricks,” he jokes in the email, while the product’s website calls the patented technology “the only functional change to the ceramic plate in centuries.”

According to Ramirez, the microwave susceptor material is red earthenware with an addition of iron filings. “Red earthenware already contains iron oxide, which is a polar molecule,” he explains. The material absorbs microwave radiation, then releases it as heat in a controlled manner according to the Stefan-Boltzmann law, the product website says. (The photo above, credit J.J. Ramirez/HotSmart USA, shows the susceptor material and the top and bottom halves of a plate.)

Plate tops and bottoms are produced separately, then joined using an unspecified adhesive with the susceptor material sandwiched inside. According to Ramirez, any shrinkage or warpage that might result from firing is addressed by the plates’ design, which uses a conical joint. The product website says the design has proved durable in months of cycling between microwave and dishwasher.

Although they are not yet being mass produced, the plates and mugs are being marketed on Amazon. Ramirez says the products have “been received very well.” The plates have also been featured as a “Reader Invention of the Month” in Popular Science magazine.

According to the website, the dinnerware’s ability to keep food hot for extended periods of time may even offer health benefits for diabetics, bariatric surgery patients who must eat slowly, people trying to lose weight, and others who simply want to practice “mindful eating,”  a way to reduce overeating that makes a practice of slow, deliberate dining. The website also calls HotSmart plates “the most hygienic plate in history,” because they lack the unglazed dry foot found in most dinnerware that “can absorb moisture and become a breeding ground for bacteria.”

HotSmart Manufacturing Instructions - Sealing options

Did I tell you HotSmart Plates are ideal for mindful eating?

ADHESIVE SEALERS

This is another option to seal HotSmart Plates; I'm sure there are many more available, all it takes is some browsing the internet and a few phone calls.

AREMCO-BOND  315-B

MIX 315-B BASE RESIN AND 315-A ACTIVATOR IN A 100 TO 5.5 RATIO BY WEIGHT. ABRADE AND CLEAN SURFACE THOROUGHLY.

APPLY A 5-10 MIL GLUE LINE AND CLAMP ASSEMBLY TO REDUCE AIR ENTRAPMENT.

 (YOU CAN STACK THE PLATES UPSIDE DOWN IN A WOODEN FIXTURE AND PUT A BRICK ON THE PLATE AT THE TOP)

ANY OF THE FOLLOWING CURE SCHEDULES MAY BE USED:

  • 2 HOURS @  100 C + 2 HOURS @ 175 C;

  • 8 HOURS @ 150 C  (I recommend this cure schedule)

Other alternatives? See:  http://www.aremco.com

(Other alternatives may be available in your country)

HotSmart Manufacturing - The adhesive sealers

Adhesive Sealers first option

Below a photograph of the sealers we have been using and they are the ingredients needed to make RF.5 which was developed in house.

The silicone creates a good double wedged or hourglass shaped seal while the RF.5 is used on the outer seal (It has a very nice appearance if you remove the excess thoroughly.
(Under construction)

Silicone RTV and AB glue
(Available in China)

HotSmart Manufacturing Instructions - Joint


Lets continue with the Manufacturing instructions

The Joint

AFTER READING THIS POST YOU WILL HAVE ENOUGH INFORMATION
(We welcome questions and may even buy part of your production for the USA market)

You may be asking yourself why HotSmart is so "kind" as to publish this? (What's the catch?)
  • First of all, patents are public knowledge anyway; just search the USPTO for Pat. 7,176, 426
  • Second we want the world to know that they don't have to eat on cold dumb plates (that get food cold) anymore. All regular plates even if preheated get cold fast.
  • IMPORTANT: In a world with obesity problems, eating slowly helps prevent overeating. Google "eating slowly yourself or you won't believe me  obesity, heart disease, diabetes, etc. (And who wants to eat slowly if food gets cold?)
  • HotSmart is looking for suppliers of different styles, shapes, patterns, materials etc.
  • HotSmart is looking for funding to grow fast; our prices are very high because we are not mass producing and even with those ridiculous high prices, we seriously doubt there will be HotSmarts for this coming Christmas of 2013. 

Adhesive sealers (alternatives)
This is just the first alternative: using Silicone RTV  and RF.5 to seal the plate which may be used in combination with RF.5 (This is what I recommend unless you have access to hi-tec epoxies which I will mention in a separate post).

(RTV is available in different colors and some companies are willing to develop the color you need).

There are many other alternatives including one that HotSmart (Myself) Developed that has nice appearance (I will talk about it on the next posts) let me advance you this:
While testing some type of Chinese A B Epoxy which has the tendency to "vitrify" and crack I thought: what if I add silicone to the mix so that the polymer interlaces with the epoxy and it does not get so hard? Well believe it or not at the second try I obtained what I call RF.5  (Ramirez Formula 0.5). It came with the right hardness and color for my HotSmart plates
  • Component A................ 2 parts
  • Component B................ 1 part
  • Clear silicone RTV........0.5 parts


Clear silicone RTV which is flexible is better for the hourglass (Double wedge) shaped seal while RF.5  may be used for appearance.

Steps for assembly:
  1. With the plate upside down, you cover all the small round area - including the boss with clear silicone RTV;  place the heater with the concave side facing the plate, fill the hole in the heater with RTV.
  2. Wait till the RTV cures (It takes several hours) DO NOT SEAL THE PLATE BEFORE IT CURES
  3.  Apply clear RTV  on the plate at the place you will form the hourglass-shaped seal
  4. Apply RF.5 to the flat surface of the base to form the exterior seal and remove the excess before it hardens completely. You want a perfect seal without excess of adhesive.
  5. That's it; make 3 components (you can even outsource them), and put them together. 
 
License required for the USA
(Get in touch)


Another alternative is using High temperature epoxy which requires some curing time in an oven but becomes practically indestructible (I will give details later).

Obviously the plate can be "slimmer" and lighter

(This is an illustrative example)





 The joint has an hour glass shape so that the pressure from either side increases the efficacy of the seal. This technique is used in bathyscaphe windows (check Wikipedia). The explanation is simple: In a conical or wedge shaped seal the more you push the better it seals; I did not invent that.

Under construction... I will update as soon as I can

HotSmart Manufacturing Instructions - Details

The Devil is in the details...

Ooops! that's with lawyers and contracts; here the details are key to success





Everybody in the business knows how to do this right? Cover the area with melted wax (The same procedure used for the "dry foot") before glazing.
The reason for this area being unglazed is that the heater -described in previous posts- is also unglazed and is attached to the lower side of the plate hanging like a ceiling fan using clear silicone RTV (Room Temperature Vulcanizing); that small round area separates the heater with precision from the plate creating a gap (gaps are very important in the cavity, I will explain later).

IMPORTANT:
The areas at the joint can also be unglazed depending on the adhesive sealer chosen (skeptics who don't believe HotSmart plates can be made dishwasher-safe ignore that even airplanes nowadays are assembled using hi-tec epoxies. Did you know that the tiles of the space shuttle were attached with silicone?). By the way, HotSmart Plates can be designed to resist lots of abuse (overheating ) by simply redesigning the internal gaps.

The radiated heat from the heater that reaches the plate is inversely proportional to the square of the distance, example:
  • If the small round area is 1 mm. thick one arbitrary unit of infrared radiation will reach the plate (lets call it one Ir (One Infrared radiation unit)
  • If the small round area is 2 mm. thick, 1/4 Ir  (0.25) one quarter of a unit will reach the plate 
  • If the small round area is 3 mm. thick 1/9 Ir  one ninth (0.11) of a unit will reach the plate.
As you can see; by increasing the gaps you can control the amount of heat released and change the shape of the temperature chart below Click it to go to "How to .." on wikiHow or simply click here

Please do not forget to RT
 

See how to use in wikiHow
  
The plate comes hot out of the microwave oven -except the rim for safe handling-  but... This is very important: By the time a HotSmart Plate reaches maximum temperature a normal plate -no matter how much you preheat it- will be cold along with the food it holds.

NOTE: A similar procedure (using melted wax) can be followed for the surfaces of the joint, depending of what adhesive-sealer you decide to use. I will dedicate a post to discuss alternatives.Yes, HotSmart Plates will be Dishwasher proof

If you are interested in becoming a qualified supplier for us or selling in the USA We (I, the inventor) will give you personal attention. My contact information is on HotSmartUSA.com

Our goal is to see a couple HotSmarts in every single home (There are over 100 million homes just  in the USA alone)  

Stay tuned and please RT

HotSmart Manufacturing Process- Upper Component

And the upper component is... drums...
A plate! Ta daa!

Yes, those are the good news and probably the main thing I want to communicate : A HotSmart®  is a plate with a heater and a base that encloses it.

Anybody making plates can make HotSmart Plates, the only plates in history that keep food hot.

http://www.HotSmartUSA.com

As a matter of fact our first working HotSmart prototypes were made buying all kinds of different plates at Wal-Mart and simply adding them the heater and the base (You need to see previous posts).

Well, obviously I made some minor modifications later to:

  • Take full advantage of the Stefan-Boltzmann law
  • Avoid any risk of cracking
  • Create a better seal between the plate and the base
  • Center the heater in the cavity, ideally the heater should not touch the walls of the cavity
  • Create better surfaces for the type of adhesive used (That requires some explanation but is easy to do).
  • Etc. (I will keep posting anything that helps that is on my notes)

Please RT so we can mass produce them or promote manufacturing and above all lower our prices, will you?

See images of upper component below
(We need  a supplier for the USA market- we also license the technology)

HotSmart Manufacturing Process - Base

Make 3 components, assemble them and you have the best ceramic plate in the world 

(You can even use your own beautiful designs slightly modified)

If you can make ceramic plates and a base like the one shown below (which is basically an small deep plate, then you can make plates that remain still HOT after more than half hour by simply preheating them in the microwave oven for as little as ONE single minute.The food will not get cold

By the way, a very important benefit is that by enjoying food slowly, mindfully you get satisfied with less food. HotSmart Plates allow you to enjoy slowly since food does not get cold. This is very important with the serious obesity problems we face almost all over the world, but I will let you research that by yourself; this is about manufacturing the best plates in the world, actually the only functional innovation to the ceramic plate in history.

It is inevitable that good restaurants adopt this type of plates; they will improve service and will save thousands in energy costs per year (They will no longer need those big plate warmers that are ON all day long). 


(under construction, I will update and post daily if I can)

Click the image to see how they work
 
Yes, I know what you are thinking; it can be made thinner as long as you follow certain guidelines (In later posts)

Will you please RT? We want to encourage manufacturing to lower the prices; many people love these plates but they are expensive (not mass produced yet).

HotSmart Manufacturing Instructions - Cavity

CAVITY IN A HOTSMART PLATE
(Details will be explained)

Click image below for more details and will you please RT? We want to encourage manufacturing to lower our prices (A license is required for the USA)








The cavity for an all purpose plate is big
You can fit a thick heater or modify the base to make a slimmer plate.

We will try to concentrate on this cavity or enclosure for the specially developed (by HotSmart) microwave absorbing material or heater which in this case is shaped like a disk.

You can of course manufacture square plates or any other shape provided you follow certain guidelines; the heater and the cavity are the key to a successful functional design..
 
You may need to see previous posts on which we explain how to manufacture the heater we will teach also the theory or working principle The Stefan-Boltzmann law maybe in lay terms and why is this heater so efficient.
