JPH01108934A - Storeroom for fresh provisions - Google Patents

Abstract

PURPOSE:To provide the above storeroom capable of storing a fresh provisions over a long period without causing discoloration of the surface skin, lowering of water content and change in taste, by supplying cooled foam to the surface skin of a fresh provisions. CONSTITUTION:A stock liquid 7 of foam is controlled at a prescribed temperature with a temperature controller 9 and foamed 6 with an air pump 8. The foam 6 is transferred to a storage chamber 1 and supplied to the surface skin of fresh provisions 3 placed in a basket container 4 on a hurdle partition plate 5.

Description

[Detailed description of the invention] This invention is a fresh food storage using foam.

Traditionally, perishable foods have been stored using water, ice, or gas.

When stored for a long time using conventional methods, the freshness deteriorates and the product value decreases.

(b) The epidermis becomes discolored.

(b) Water content decreases.

(c) Taste changes.

As a result, the product value has decreased.

The present invention has solved these strong demands by using a method using foam.

Hereinafter, this will be explained. First, water cooled to a required temperature is sprayed to bring the storage room and fresh food to the required temperature.

Next, by constantly supplying foam that has been cooled to the required temperature to the entire surface of the fresh food before the skin of the fresh food dries out, [a] it provides moisture and a certain necessary temperature to the skin of the fresh food, thereby increasing the temperature of the skin. Can prevent discoloration [mouth] Foam film can prevent moisture loss [c] By using bubbles to remove minute gases released from the skin of fresh foods, changes in taste can be reduced. In particular, in the ice-temperature storage method described in claim 2 of the present patent, since bubbles can be kept at a constant temperature relatively easily, the temperature difference between the central part and the peripheral part of the storage chamber can be set to 0.1 or less. Can be kept at freezing temperature for a period of time. This was extremely difficult using conventional methods. Improvements in freshness and product value that could not be achieved with conventional methods can be seen.
