How to market a technology?A German Pool Case Study on Applying Far Infrared Technology to Cooking Appliances.

Application of the FIR Technology - Electrical appliances- Kitchen appliances

(e.g. toaster, oven, water heater, steam oven, stove, electric rice cooker, coffeepot, thermos, etc.)

- Electrical heaters for warming human body(e.g. different types of heating systems, heating blanket for healthness, in-car heating cushion, foot warmer, etc.)

- Appliances for electrical refrigerating and cooling products(e.g. heat absorbing systems, e.g. electrical refrigerator, air conditioner, red wine storage cabinet, etc.)

- Health, personal body care and cosmetic(e.g. far infrared rays lamp to relief muscle ache, hair blower, facial steamer, cosmetic systems, etc.)

- Other domestic heating electrical appliances (e.g. tumble dryer)

- Heat transfer occurs through: conduction, convection, and radiation.

- Every method of cooking involves one or more of these heat transfer methods.

Cooking

Conduction

- Exchange of thermal energy through direct contact between a heating element and the food;

- Different materials result in different heating times and temperatures;

- Pan-frying or sauting are common forms of conduction.

Convection

- Heat is transferred by the movement of molecules in either gas or liquid.

- Baking and roasting are common forms of convection cooking. The heating elements within the oven heat the air and that comes in contact with the food.

- Heat transfer methods that do not need a medium.- Infrared radiation transfers thermal energy in the form of

electromagnetic waves.

Radiation

It is considered that meat and fish cooked by charcoal or bread baked in a stone oven are more delicious than those cooked in a conventional gas oven

Heating using FIR heaters is a heating method that is similar to the charcoal or stone oven, and thus it may produce delicious foods.

The direct penetration ability of infrared radiation makes it possible to increase the energy flux without burning the surface and thus reduces the necessary heating time that conventional heating methods require.

(Infrared processing C. Skjldebrand, ABB and Lund University, Sweden)

Advantages of infrared radiation over conventional heating :

- High heat transfer capacity- Heat penetration directly into the product- Faster heating rate- Shorter response time- Uniform drying temperature- High degree of process control- Cleaner working environment- Can be applied to various food processing operation namely drying, baking, roasting, blanching, pasteurization and sterilization.

When radiant electromagnetic energy impinges upon a food surface, it may induce changes in the electronic, vibrational,and rotational states of atoms and molecules.

Changes in the electronic state: wavelengths 0.2 to 0.7um Changes in the vibrational state: wavelengths 2.5 to 100umChanges in the rotational state: wavelengths >100um (microwaves)(Thermal Food Processing: New Technologies and Quality Issues, Noboru Sakai and Weijie Mao)

Generally, food is composed of water and organic compounds such as carbohydrates, proteins, and fat, and the infrared absorption characteristic of those materials is important;

The IR energy in proportion to the vibrational frequencies (wave length) is efficiently absorbed in a body.

(Thermal Food Processing: New Technologies and Quality Issues, Noboru Sakai and Weijie Mao)

Normal vibration of water

Amino acids, polypeptides, and protein: reveal 2 strong absorption bands

localized at 3 to 4 and 6 to 9 um

Lipids: reveal 3 strong absorption bands localized at 3 to 4 , 6, and 9 to10 um- show strong absorptionphenomena over the entire radiation spectrum

Carbohydrates:- yield 2 strong absorption bands Centered at 3, and 7 to10 um

Data on absorption of infrared radiation by the principle food constituents can be regarded as approximate values due to a lack of information.

Principal absorption bands of the main food components compared with water (Sandu 1986)

The effect of IR radiation on optical and physical properties of food materials is crucial for the design of an infrared heating system and optimization of a thermal process of food components.

In order to achieve energy optimum and efficient practical applicability of IR heating in the food processing industry, combination of IR heating with microwave and other common conductive and covective modes of heating holds great potential.

Comparative Performance Characteristics of FIR Oven and Conventional Oven

FIR Oven Conventional Oven

The grilling time is reduced by approximately half. As the energy consumption of the griller per unit time is the same, the energy consumption is reduced by half. Furthermore, the grilled condition is satisfactory and the yieldincreases by approximately 10%, so the economic effect is great.

Energy Efficienttransfers heat to food by means of FIR wave, convection, and conduction all at one time. As a result, food can be cooked within a much shorter time.

Healthy CookingNo oil is needed during preparation and cooking process. Heat waves can penetrate directly into meat. It effectively drives out fats and reduces grease within food.

Sensational cooking resultCan cook food fast and evenly from the inside out.

Safe & Easy Operation

1) Selective heating: IR heating can be controlled or filtered to allow radiation within a special spectral range to pass through using suitable optical band pass filters. Such a controlled radiation can stimulate themaximum optical response of the target object when the emission band of IR = the peak absorbance band of the target object.

2) IR heating is a unique process; however, presently, the application and understanding of IR heating in food processing is still in its infancy. Detailed insight into the theoretical explanation of IR effects: interaction with food components, change in taste and flavor
