Embodiment Construction

[0028] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0029] The low-temperature dehydration of ice cream is divided into three processes: system configuration, sublimation of ice crystals, and water evaporation.

[0030] (1) System configuration process

[0031] (1) Divide the ice cream into blocks, the size of which can be determined according to the needs, but the size of a pair of standard playing cards is the best, that is, 9 cm x 6.5 cm 1.5 cm;

[0032] (2) Pack the ice cream processed in the above step (1) with an open container without sticking to each other, and have enough area to be in contact with the atmosphere so as to facilitate the sublimation of the ice crystals. The container can be made of plastics that meet food hygiene requirements, Made of paper, alloy and other materials;

[0033] (3) deep freezing the ice cream processed in the above step (2) to the range of minus 20°C ...

Abstract

A method for preparing the ice cream able to be stored at ordinary temp includes such step as cutting for dividing ice cream, loading in open container, freezing at -20--60 deg.C, putting it in a sealed low-temp drying system with controllable temp, pressure and humidity, ice crystal sublimating at -3--7 deg.C, regulating the dewatering speed, baking, and packing for isolating the fruit from atmosphere.

Description

technical field [0001] The invention relates to the field of processing of freeze-dried food, in particular to the field of processing of ice cream, in particular to a processing method of ice cream which can be stored at normal temperature. Background technique [0002] Ice cream is a kind of frozen snack food and is deeply loved by people. Since the invention of ice cream, they have to be preserved at low temperatures and eaten frozen. It is also difficult to keep fresh after being frozen for a long time. At room temperature, they melt into a liquid very quickly and go bad very quickly. Therefore, they are not easy to preserve and difficult to transport, and they must be stored and transported by means of refrigeration equipment, which has become the law of people's cognition. [0003] So is there a way to dehydrate the ice cream before it melts, since there is no water, it is impossible for the ice cream to melt at room temperature. Like this, people just do not need ...
