Problems solved by technology

[0004] Adopting method 2), the cold stimulation of meat and poultry caused by excessive cold water showering in some parts is not good for poultry meat quality, and the temperature of other parts cannot be effectively cooled. The actual air volume acting on the meat and poultry is insufficient, and the ventilation and cooling effects are not ideal; the limitation of method 1) is that the cooling time is too long, and the heat stress cannot be effectively relieved, and the phenomenon of meat and poultry dying before slaughter often occurs

Abstract

The invention discloses a device and method for reducing heat stress in poultry transportation in summer. The device is characterized by comprising a cooling chamber (1) and a cooling device (2); the cooling device (2) comprises a water supply unit (3), a spraying-ventilating unit (4) and a circuit unit. The method is a cooling method through using the device. According to the device and method for reducing the heat stress in poultry transportation in summer, fans (comprising a suction fan and axial flow fans) are used in combination with atomizing spray heads, so that the effects of atomizing spraying, three-dimensional ventilation and rapid cooling are achieved; processing quality of slaughtered poultry is effectively guaranteed, the conditions of water loss and meat quality softening are improved, meanwhile, production cost of an enterprise is reduced, and the needed device is simple, easy and convenient to operate, high in operability and suitable for being widely popularized and applied.

Description

technical field [0001] The invention relates to a device and method for reducing heat stress during summer transportation of meat and poultry, and belongs to the technical field of environmental control systems, in particular to a device and method for anti-heat stress for the heat stress generated during the transportation of meat and poultry in summer. Background technique [0002] Under high temperature conditions in summer (ambient air temperature > 30°C), broiler poultry will experience heat stress due to their inability to adapt to the high temperature during transportation. The concept of so-called heat stress is that when the ambient temperature exceeds the upper limit of the heat zone of poultry (excessive temperature, the excessive temperature of poultry is generally around 32 degrees, which is closely related to the breed, age, and hunger state of the poultry), the body will Heat dissipation is hindered, physical regulation cannot maintain a constant body tempe...
