Abstract

A vegetable and/or fruit refrigerator comprised of an outer tank fitted with polyurethane foam in it's inner side;an inner tank;a middle tank fitted upon any one side of the inner tank and comprising of cooling tubes for flow of refrigerant and a hole for filling water; a thermal conductivity paste being applied in between the space between the inner and middle tanks; the said water filled into the middle tank being cooled when refrigerant is passed in the said cooling tubes which cooling is dissipated to the inner tank through a paste medium and eventually to the said vegetables/fruits placed inside the inner tank;a hinged door is fitted with glass for preventing the loss of cooling

Full Text	The invention pertains to the field of refrigeration engineering, more particularly to vegetables and fruit refrigerator for use in Supermarkets, Houses and hotels. Precisely the invention relates to a refrigerator for use in super markets and cold storages. The main object of this invention is to keep the garden freshness of the vegetables/fruits for a very long time without shrinkage. Presently in supermarkets, vegetable and fruits are usually preserved in the ordinary refrigerators which are also used for preserving other food products, medicines, etc. The exact temperature and humidity required for the fruits and vegetables cannot be maintained in this refrigerator, so fruits and vegetables get damaged easily. The new invention is more economic and more compact to preserve the fruits and / or vegetables for a long time without any shrinkage. According to the inventor, the invention is a vegetable and/or fruit refrigerator comprised of an outer tank fitted with polyurethane foam in it's inner side; an inner tank; a middle tank fitted upon any one side of the inner tank but not in the bottom and comprising of cooling tubes for flow of refrigerant and a hole for filling water; the thermal conductivity paste is applied in between the space between the inner and outer tanks; the water filled into the middle tank is cooled when refrigerant is passed in the said cooling tubes which cooling is dissipated through a paste medium to the inner tank and eventually to the said vegetables/fruits placed inside the inner tank. A hinged door is fitted with glass for preventing the loss of cooling. Fig I describes the nature of the invention and the manner in which it is to be performed. The invention is comprised of an outer tank(1), a middle tank(4) and an inner tank(3). A polyurethane foam(2) layer is fitted in the inner side of the outer tank(1). The middle tank(4) is fitted upon any one side of the inner tank(3) but, not upon the bottom side. The cooling coil(5) is fitted upon the middle tank. The middle tank has a hole means through which water is filled into the middle tank(4). The middle tank(4) is fitted on the inner tank(3) and a thermal conductivity paste(9) is applied in the space between middle(4) and inner(3) tanks. The thermal conductivity paste is a composition of petroleum distillate, calcium carbonate and kaonnine. The primary object of this invention is to preserve the garden freshness of the vegetables and fruits. The vegetables and fruits harvested from the garden start shrinking in a few days if the vegetables and fruits are preserved by conventional refrigerants directly. When the conventional refrigerants are passed upon the vegetables and fruits they get shrinkage within a day or two. When this new invention is applied, the vegetables and fruits are not directly cooled by the conventional refrigerants, alternatively, the conventional refrigerants are used to cool the water(6) filled in the middle tank(4) and the water(6) dissipates the cooling to the inner tank(3) which cooling eventually cools the vegetables/fruits placed inside the inner tank(3). The inventor in order to cool the water kept in the middle tank(4) fitted cooling tubes upon this middle tank, by soldering or welding process as the case may be. The water(6) filled in the middle tank(4) is cooled when the refrigerant is passed in the cooling coil(5) . The flow of refrigerant cools the water(6) filled in the middle tank(4) and the water dissipates the cooling to the inner tank through a thermal conductivity paste(9) medium which cooling eventually dissipates the cooling to the vegetables kept in the inner tank . This process of cooling the vegetables indirectly helps in keeping the garden freshness of the vegetables for a very long time, and preserves the vegetables and fruits from shrinkage. The vertical vegetable refrigerator has a hinged door (7) fitted with the glass (8) which prevents the loss of cooling. The glass door (8) will display the vegetable stored in the refrigerator. Normally refrigeration compressors are designed so that refrigeration gas will vaporize at 4 degree centigrade, if this refrigeration gas is used for cooling the vegetables directly, the moisture contents in the vegetable will condense and eventually the vegetables start shrinking. To avoid this, water (6) is filled in the middle tank (4). The flow of refrigerant transfers the cooling to the water and the water cools the vegetables kept in the inner tank indirectly. This process of cooling the vegetables indirectly helps in keeping garden freshness of the vegetables for a very long time, and preserves the vegetables and fruits from shrinkage. The vertical vegetable refrigerator has a hinged door (7) fitted with glass or metal (8) which prevents the loss of cooling. The glass door (8) will display the vegetables stored in the refrigerator. 1 CLAIM 1. A vegetable refrigerator comprising of an outer tank fitted with polyurethane foam in it's inner side; an inner tank; a middle tank fitted upon any one side of the inner tank and comprising of cooling tubes for flow of refrigerant and a hole for filling water; a thermal conductivity paste is applied in between the space between inner and middle tank; the water filled in the middle tank is cooled when the refrigerant is passed in the said cooling tubes, which cooling is dissipated through the inner tank and eventually to the said vegetables/fruits placed inside the inner tank; a hinged door is fitted with glass for preventing the loss of cooling. 2 A vegetable refrigerator as claimed in Claim 1 wherein a hinged door is fitted with glass for preventing the loss of cooling. 3. A vegetable refrigerator as claimed in Claim 1 wherein copper cooling tubes are fitted upon the middle tank 4. A vegetable refrigerator as claimed in Claim 1 wherein a thermal conductivity paste applied between inner and middle tanks. 5. A vegetable refrigerator substantially as herein described and illustrated with reference to the accompanying drawing.
