Abstract
A method and device for heating and cooling, such as for the sterilization, pasteurization, drying and/or roasting, of food products, such as nuts and beans, for example whole and crushed peanuts and coffee and cocoa beans, comprising bringing the raw food products into contact with a heated granular material, separating of the granular material from the food products after the heat transfer from the heated granular material to the food products, and the subsequent cooling of the food products, the cooling of the food products taking place by means of a granular material which is first conveyed to the product to be cooled and is separated therefrom after the cooling.
Claims21
Method of heating and cooling raw food products comprising:
- a) heating a raw food product by contacting the food product with heated, non-food, granular material;
- b) cooling the heated food product;
- and
- c) separating the food product from the granular material
- wherein the heating or cooling of the food product during step a), or step b) respectively, is effected by contacting the food product with a heat transfer material comprising porous granular zeolite, the granular zeolite being at a different temperature from the temperature of the food product.
A method of sterilizing, pasteurizing, drying or roasting a food product selected from the group consisting of nuts, beans, whole peanuts, crushed peanuts, coffee beans and cocoa beans the method comprising:
- a) heating a food product by contacting the food product with warmer granular material;
- b) cooling the heated food product by contacting the food product with cooler granular material;
- and
- c) separating the granular material from the cooled food product;
- wherein the granular material in both steps a) and b) comprises a zeolite having a pore size such that water vapour is adsorbed in preference to large-molecule compounds and wherein the zeolite releases heat upon adsorption of water vapour.
Method of heating and cooling raw food products that release water vapor on heating, the method comprising:
- a) heating the raw food product by contacting the food product with heated, non-food, granular material;
- b) cooling the heated food product;
- and
- c) separating the food product from the granular material
- wherein the heating or cooling of the food product during step a), or step b) respectively, is effected by contacting the food product with a granular heat transfer material having a pore size such as to preferentially adsorb water vapor wherein the granular heat transfer material releases heat during the adsorption of water vapour.
