Low temperature and high humidity thawing method

Abstract

The invention belongs to the technical field of meat thawing, particularly relates to a low temperature and high humidity thawing method. According to the method, a thawing room is used to thaw meat products as following steps: 1, using steam to adjust the temperature of the thawing room to 17-19 DEG C and the surface temperature of meat products to -6 DEG C; 2, adjusting the temperature of the thawing room to 15-17 DEG C and the surface temperature of the meat products to -4 DEG C; 3, adjusting the temperature of the thawing room to 13-15 DEG C and the surface temperature of the meat products to -2 DEG C; 4, turning on air intaker and air discharger to ventilate for 10 minutes and adjust the temperature of the thawing room to 11-13 DEG C and the temperature of central temperature of the meat products to -2 DEG C; 5, maintaining the temperature of the thawing room at 9-11 DEG C until surface temperature of the meat products reach to -1 DEG C, ventilating for 20 minutes to adjust the temperature of the thawing room to 6-7 DEG C and the central temperature of the meat products to -1 DEG C, ending defrosting; and 7, maintaining the temperature of the thawing room at 2 DEG C for storage and preservation. The thawing method provided by the invention can reduce bloody water flowing during thawing, and improve utilization rate and freshness of the meat products.

Description

technical field [0001] The invention belongs to the technical field of meat thawing, and in particular relates to a high-humidity low-temperature thawing method. Background technique [0002] At present, frozen meat processing enterprises generally rely on steam flow and direct heating when thawing frozen meat. The bloody water will cause a large loss of nutrients such as protein in frozen meat, and the outflowing bloody water will affect the sanitation of the thawing warehouse, resulting in increased cleaning costs and serious pollution to the environment. Contents of the invention [0003] The purpose of the present invention is to provide a high-humidity low-temperature thawing method to solve the above-mentioned defects in the prior art. [0004] To achieve the purpose of the present invention, the present invention provides a high-humidity low-temperature thawing method, comprising the following steps: [0005] 1) Steam enters the thawing room, and the fan is turned...
