Semi-finished roast duck airing device

Abstract

The invention discloses a semi-finished roast duck airing device which belongs to the technical field of food processing and is used for unfreezing and dewatering semi-finished roast ducks by airing. The device comprises a box body, an airflow circulation system, a refrigeration system, a hanging system and a control system. A semi-finished roast duck airing room is isolated from the outside by the movable box body with favorable heat-insulating property, a line of semi-finished roast duck hanging hooks are arranged on the top board of the box body in the semi-finished roast duck airing room for hanging the semi-finished roast ducks, and the semi-finished roast ducks are rotated for being aired and dewatered uniformly. The airflow circulation system forces the air in the box to blow onto the semi-finished roast ducks at certain airflow speed, the refrigeration system is used for controlling the airing temperature and ensuring the temperature required for unfreezing and dewatering the semi-finished roast ducks by airing, and the control system controls and adjusts the airing temperature, the airing speed and the rotary speed of the semi-finished roast ducks. The device can set the semi-finished roast duck airing temperature, the airing speed and the rotary speed of the semi-finished roast ducks, prevent the semi-finished roast ducks from being polluted by flies and dust, overcome the influence of weather change and single-direction airflow on the semi-finished roast duck quality, and realizes the mechanization and standardization of unfreezing and dewatering the semi-finished roast ducks by airing.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a roast duck drying device. Background technique [0002] "If you don't go to the Great Wall, you are not a hero. It's a pity if you don't eat roast duck." "Beijing Roast Duck" is not only a business card of the capital Beijing, but also a representative of the extensive and profound Chinese food culture. There are many factors that affect the roasting effect of "Beijing Roast Duck". "Peking Roast Duck" has to go through duck selection—slaughter and hair removal—inflating—incision and gut removal—washing and hooking—frozen storage—thawing and drying— -Scalding and pouring caramel sugar-roasting and other production techniques can finally bake the "Beijing Roast Duck" with good puffing effect, good color, fragrance and taste. Each process link has an important influence on the formation of roasted taste. The role of pumping air is to fully expand the gas fill...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the existing problems of thawing and airing of roast duck, solve the problem of thawing and airing of "Beijing Roast Duck" duck blanks in summer and autumn high temperature and high humidity seasons, and improve the thawing and airing of "Beijing Roast Duck" duck blanks The degree of automation of dehydration provides a roast duck drying device. The roast duck drying device includes a box body, an air circulation system, a refrigeration system, a suspension system and a control system. Divided into an air distribution chamber 6, a billet airing chamber 10 and a return air chamber 9, and the retrieving door 2 is installed on the front of the billet airing chamber 10; On the top plate, the duck blank hanging hook 11 is rotatably connected with the box top plate, and the duck blank rotating motor 12 is coaxially connected with the duck blank hanging hook 11 on the box top plate; the centrifugal fan 5 of the air circulation system is placed in the return air chamber 9, The air outlet of the centrifugal fan 5 is on the intermediate partition 3 at the bottom of the air distribution chamber 6, the nozzles 7 are distributed on the air distribution plate 4, each group of nozzles 7 corresponds to a duck billet hanging hook 11, and the return air pipeline 8 passes through the air distribution plate 4. The intermediate partition 3 at the bottom of the billet chamber 10; parts such as the compressor 13, condenser and throttle valve of the refrigeration system are placed outside the casing, and the evaporator of the refrigeration system is placed on the two side walls in the billet chamber 10 for drying. The machine 13 and the evaporator are connected with a refrigeration pipeline; the controller 14 of the control system is placed outside the casing, and is composed of a temperature control circuit, a wind speed control circuit and a duck base rotation speed control circuit, and the temperature sensor of the temperature control circuit is placed in the drying room 10, the temperature lead wire is connected with the temperature control circuit, the temperature control circuit is connected with the compressor 13, the wind speed control circuit is connected with the centrifugal fan 5, and the duck blank rotation speed control circuit is connected with the duck blank rotary motor 12
