All thermal devices (the obzharochny furnaces sterilizing devices) isolate. Temperature of an external surface of thermal isolation should not exceed 40-45C. During the operation of furnaces watch the constant level of oil and water, it is forbidden to bend to oil.
Quality of a surface of packages, except seams, has to conform to requirements of standard documentation of polymeric materials from which they are issued. Internal surfaces of packages should not stick together.
Other defect of frozen fillet arising in the course of storage this yellowing of fat as a result of its oxidation. In the beginning yellowing has superficial character, then yellowish congestions are formed. Gradually yellowing gets under skin into muscular tissue, impacting to a product unpleasant relish. Oxidation of fat develops as a result of long storage of frozen fillet and is accelerated under adverse conditions. Fast development of oxidation is promoted by also raised content of salt in a blanket of fish.
Accept the working length of the conveyor of equal 4,3 m (for constructive reasons), then the full length of the conveyor, taking into account length of driving and tension station, and also the distance ensuring safety at service of the conveyor approximately will make about 7 meters.
Fish before processing will be stored in water in the ratio respectively. Then the volume of the bunker will consist of the volume of fish and volume of water taking into account bunker efficiency (0. A storage time of fish raw in the bunker 2,5 hours.
Primary instructing on a workplace consists of two stages. The first stage is carried out by the senior safety measures corresponding instructions instructor. Instructing is carried out for the purpose of acquaintance instructed with safety requirements in relation to this enterprise.
L = 8/(2 * = 4 m, thus the full length of the conveyor, taking into account length of driving and tension station, and also the distance ensuring safety at service of the conveyor approximately will make about 7 meters, but for constructive reasons accept 10 meters.
For prevention of defects of frozen fillet, being result of unsatisfactory quality of fish raw, it is necessary to direct on processing fish of high degree of freshness – live, just fallen asleep, in a condition of a posthumous okocheneniye, in an initial stage of an avtoliz. Fish with far come process of an avtoliz it is not necessary to process.
The operation purpose - to keep quality of a product before realization. It is necessary to store frozen fillet at a temperature not above minus-18 C. The period of storage of the fillet packed into polymeric packages under pressure is equated to a period of storage of the glazed blocks of fillet and makes for fillet of a pollock of 5 months.
L = 3*1 = 3 m, but accept length of 4,8 m for constructive reasons, thus the full length of the conveyor, taking into account length of driving and tension station, and also the distance ensuring safety at service of the conveyor approximately will make about 7 meters.
Repeated instructing is carried out by chiefs of shops with involvement of experts at least once in 3 months after primary instructing in the program of the second stage of primary instructing with analysis of cases of violations of instructions or labor discipline.
Sharp fluctuations of temperature of storage, especially towards increase as they accelerate undesirable changes of proteins and fats of fillet have an adverse effect on quality of frozen fillet, and also lead to recrystallization of ice and increase of shrinkage of fillet. Therefore temperature of storage has to be not only rather low, but also be supported at the constant level, with the fluctuations which are not exceeding 1-2C.
Fillet with sharply expressed signs of an avtoliz when freezing has dark color, the grown dull surface, the weakened meat consistence after defrosting. If after defrosting the consistence of meat is flabby, fish consider non-standard.
B = G/(3,6*V*q) = 0,555 / (3,6*0,5*28,2 = 01m. Considering that the average length of a fileychik with a piece weight of 0,8 kg is equal about 300 mm, accept width of a tape of equal 300 mm that gives the chance to be developed to fileychik on a tape.
