Working method of pork refrigeration equipment

Abstract

The invention belongs to the field of refrigeration devices and specifically relates to a working method of pork refrigeration equipment. The equipment comprises a cabinet; a top of the cabinet is hinged with a cover plate for sealing; multiple air pumps are installed at the bottom of the cabinet with intervals; the air pump is provided with a rubber pipe; the rubber pipe is provided with an air pipe therein; the air pipe is connected with an output end of the air pump; a top of the rubber pipe is provided with a ball; the circumferential surface of the ball is provided with a plurality of through grooves; the inside of the ball is provided with an expansion sleeve; a surface of the expansion sleeve is provided with a plurality of spurs in the through grooves, and the expansion sleeve is connected with the air pump; a refrigerator for cooling is provided at the upper portion of the side wall of the cabinet; a water tank is arranged in the side wall of the cabinet; a side wall of the cabinet is provided with a horizontal tube leading to the inside of the cabinet; the horizontal pipe is connected with the water tank, and an impeller driven by the motor is arranged between the horizontal pipe and the refrigerator; the edge of the impeller abuts the outlet of the horizontal tube. This program can avoid pork adhesion, prevent pork damage and keep pork moisture.

Description

technical field [0001] The invention belongs to the field of freezing equipment, and specifically discloses a working method of pork freezing equipment. Background technique [0002] As the main source of meat for Chinese residents, pork accounts for more than 60% of meat consumption products. Because it is rich in nutrients, it is suitable for the growth and reproduction of microorganisms, and it is easily polluted by microorganisms in the environment during its production, processing, transportation and sales. Thereby leading to spoilage and shortening of shelf life; the safety of pork products is more and more concerned by consumers, so the freezing and fresh-keeping measures of pork seem to play a decisive role in the industrial chain of pork products. After the pigs are slaughtered, the pork pieces that are divided into pieces will deteriorate 3 days after the pigs are slaughtered, so the pork must be frozen. The existing market basically uses frozen storage and transpo...

Problems solved by technology

After the pigs are slaughtered, the pork pieces that are divided into pieces will deteriorate 3 days after the pigs are slaughtered, so the pork must be frozen. The existing market basically uses frozen storage and transportation, but when the pork is frozen, due to the freezer The body is forcibly cooled by the refrigeration equipment, and the water in the original box condenses into ice, which leads to a decrease in the relative humidity of the air around the pork, which will cause the water in the meat of the pork to separate out, causing the moisture of the pork itself and the taste of the meat to deteriorate, reducing the The reputation of this pork in the hearts of consumers is unfavorable for production and sales; moreover, pork pieces are easy to coagulate and stick together in the freezer, and when the low temperature is frozen, the pork pieces are frozen or frozen when they are in contact with each other, making the pork The meat between the pork pieces gradually changes from soft to hard during freezing, and the volume between the pork pieces and the pork pieces shrinks under the action of freezing, and the ice cubes covering the pork will squeeze the pork, making the pork The meat quality is further adhered. After the adhesion time is too long, it is difficult to separate the pork. If a strong separation is used, the pork will be torn and the pork pieces will be broken, which will affect the quality and appearance of the pork.
