From the enclosed curd producing tank (1), which serves among otherthings to protect the milk from airborne infection during the long (16 – 20 hours) or relatively short (5 hours) coagulation period, the whey-curd mixture is pumped via a static whey strainer (3) to a cooling/washing (CW) tank (4).While the whey is passed to a collection tank, the curd falls into the CW tank with a certain level of fresh water. Even before all the curd from the cheese tank has been transferred to the CW tank, fresh water is pumped in through the bottom inlet. At a certain level in the tank, there is an outlet for the surplus liquid, which passes an inner, perforated part so that the curd is retained.After some minutes, when the surplus liquid is more or less free from whey, the inflow of water is stopped and the water is circulated through a plate heat exchanger (2), where the temperature is gradually lowered to 3 – 4 °C. The whole cooling and washing procedure takes about 30 – 60 minutes, not including filling and emptying of the CW tank.After washing and cooling, the curd is pumped via a drainer (5) to a creamer (6), designed for mixing the curd and cream dressing. Finally, the creamed Cottage cheese is packed in cups and stored in containers
