Red Water Chiller is mainly used for red water circulation cooling carcasses produced by poultry slaughtering line (2000-13500birds/h). By adopting ejecting liquid supply technology, structure design of falling film shell and tube heat exchanger, careful selection of control elements, and rigorous setting of control program, the device can provide stable and reliable ice water at about 0.3~1℃.To fully guarantee the chicken water's reasonable, pre-cooling time, poultry ketone body can be cooled to below 4℃; At the same time, the low water temperature effectively inhibited the microbial reproduction.
