Deodorization is performed with the aid of a deodorizing heater which uses a conventional glass pipe heater having a

deodorizing function.

1. Operation

The deodorizing system is arranged in the cool air passage, so that deodorization effect is always maintained.

Therefore, any operation is not necessary.

2. Component Parts and Deodorizing Principle

(1) This deodorizing heater uses the porous catalyst layer laid on the surface of radiant heater glass pipe (high-

quality quartz glass). The deodorizing catalyst consists of zeolite, alumina, silica, noble metal, and rare-earth

oxide. It adsorbs and decomposes the following odors.

It adsorbs:

Stench odor evolved from vegetables and fruits ... Methyl mercaptan,

Stench odor evolved from meats and fishes ... Trimethylamine,

Stench odor evolved from fermentation foods ... Aliphatic acids.

The noble metal and rare-earth oxides act as catalysts which oxidize and remove the adsorbed stench

ingredients at a temperature of over 250˚C.

(2) In normal cool state, this deodorizing heater adsorbs the stench ingredients. In defrosting state where the

heater is heated, it oxidizes and removes the adsorbed stench ingredients by a catalysis.
