Description

Thawing cabinet for frozen meat

Technical Field

The utility model relates to a thawing apparatus technical field specifically is a cabinet that unfreezes for freezing meat.

Background

The thawing is the reverse process of the freezing, the freezing is to change water in the food into ice, the ice is to be changed into water when the food is thawed, the quality of the food is influenced by the speed of thawing, and for the common frozen food, if the thawing speed is too high, the moisture in the intercellular space (namely outside the cells) does not have enough time to flow back into the cells again, so that the juice is lost, the quality of the food is reduced, and it needs to be noted that the quality of the thawing effect is not only related to the time and the quality of the food, but also related to the edible safety of the thawed food;

when the food is frozen, the activity of microorganisms in the food is basically inhibited, however, in the process of thawing, along with the rise of temperature, the microorganisms start to recover and the activity is enhanced, the temperature range generally suitable for the growth and the propagation of the microorganisms is 5-60 ℃, and if the thawing process is always in the temperature range, the potential safety hazard is undoubtedly increased for the food;

the existing unfreezing method comprises unfreezing modes such as natural unfreezing, warm water unfreezing, steam unfreezing, refrigeration unfreezing, microwave unfreezing and the like:

in the cold storage thawing, the meat product is placed in an environment of about 4 ℃ for a long time, the quality after thawing is good, but the thawing time is long, the natural standing thawing is an undesirable thawing mode because the meat product is in a range of 5-60 ℃ for a long time, compared with the natural standing thawing, the thawing temperature adopted by the warm water thawing is the same as the optimal propagation temperature of microorganisms, so the thawing mode is also not desirable, the steam thawing uses steam (the temperature is usually higher than 60 ℃) and although the thawing time is short, on one hand, the meat is scalded and the fruits and vegetables are softened due to the overhigh temperature, the microwave thawing uses the property that water molecules can rotate under the action of an alternating electric field to produce friction heat to thaw food, the thawing speed is high, but the overheating effect is easy to occur, namely, the interior of the food can not be thawed by microwaves, but the outer surface is already overheated, and the overheating can denature protein or change the texture structure, thereby reducing the quality of the food.

In the prior art, the food unfreezing device with the application number of CN201821543217.7 comprises a unfreezing cabinet, wherein gaskets are adhered to two sides of the outer wall of the bottom of the unfreezing cabinet, and the gaskets are respectively positioned at four corners of the outer wall of the bottom of the thawing cabinet, the thawing cabinet consists of a water storage chamber and a thawing chamber, a filter screen is arranged between the water storage chamber and the thawing chamber, a heater is arranged at the middle position of the bottom of the water storage chamber, a water inlet is arranged at the position of the outer wall of one side of the water storage chamber close to the top, and the inner wall of the water inlet is provided with a water inlet pipe, the inside of the water inlet pipe is provided with a spring plate, the top of the water inlet pipe is welded with a water inlet hopper, a liquid level meter is arranged on one side of the outer wall of the water storage chamber, which is far away from the water inlet pipe, the device can accelerate the circulation speed of water vapor, so as to unfreeze food fast, can overturn and accelerate the speed of unfreezing to food, can unfreeze and avoid causing the waste of water resource through the bottom to food.

However, the food thawing device has the following obvious defects in the using process: 1. the device heats a frozen object by heat generated by steam, however, in the actual production process, the temperature of the steam is high, the steam is condensed on the surface of a frozen product and releases heat, the high temperature is easy to cure the surface of the meat product, meanwhile, because the temperature is conducted from the surface to the inside, the temperature inside the meat product is usually between 20 and 50 ℃ in the unfreezing process, and the temperature is the optimal temperature for bacterial breeding, so the unfreezing method can not only damage the surface of the meat product, but also lead bacteria inside the meat product to breed in a large quantity, thereby reducing the storage time and the quality of the meat product; 2. the unfreezing method of the device is single, scientific and efficient unfreezing cannot be achieved, and the quality of the unfrozen meat product is difficult to guarantee.
