There are all kinds of tins in supermarkets, and fish tins are often loved by people. This is not only because of the convenience of carrying fish tins, but also because when we are away on business, we can catch the greedy in our stomach. These tins of tinplate can not only ensure the nutrition of fish, but also ensure the long-term storage of the tins without adding preservatives after being sterilized in the high temperature of the sterilization pot, so as to facilitate the fish can manufacturers to create greater profits.
Operating instructions
In general, this kind of horizontal sterilizer is used in canning factory when it is used to heat and sterilize the can under normal pressure. The equipment can realize counter pressure sterilization by introducing compressed air. If the cooling needs to be carried out in the pot, the water must be pumped into the spray pipe (or water circulation system) on the top of the pot. 　　
During sterilization, the pressure inside the can will exceed the pressure outside the can (in the pot) due to the temperature rise of the can caused by heating. Therefore, in order to avoid the pressure jump in the glass bottle and the bulge on the two ends of the tin can, the counter pressure must be applied, especially for the meat can which needs higher sterilization temperature. The use of counter pressure sterilization, that is to use compressed air into the pot to increase pressure, to prevent can convex and jump cover, its operation is described as follows: because the compressed air is a bad heat conductor, the steam itself has a certain pressure. Therefore, in the process of heating up during sterilization, compressed air is not put in, but only when it reaches the sterilization temperature and is kept warm, compressed air can be put into the pot to increase the pressure of 0.5-0.8 atmosphere. After sterilization and cooling, stop supplying steam and put cooling water into water spray pipe. The pressure of compressed air is used to compensate for the decrease of internal force of the boiler due to the decrease of temperature and condensation of steam in the boiler. 　　
In the process of sterilization, attention should be paid to the initial exhaust, and then the steam, so that the steam flow. It can also be deflated every 15-20 minutes to promote heat exchange. In a word, it must meet the requirements of sterilization conditions, and carry out according to certain procedures. The sterilization temperature, sterilization pressure, sterilization time and operation methods are specified by the sterilization process of canned products.
Installation instructions
(1) Installation foundation of equipment: the installation floor can be lowered appropriately as required to balance the rail car and height with the floor, so as to facilitate the cart to push into the pot.
(2) Install the safety valve on the boiler as shown in the drawing. Before the equipment leaves the factory, it has been adjusted to the starting pressure of 0.27MPa (hydraulic test pressure). The user can retest, but it is not allowed to raise the starting pressure at will.
(3) If the superheated water heating medium is used, the cooling water supply pressure is 0.4 MPa ～ 0.5 MPa. In order to ensure sufficient water source and pipeline water supply pressure, users are requested to add a reservoir and a pressure pump by themselves. Check valve shall be installed at the water inlet pipe to prevent the water inlet valve from leaking into the water supply pipe when the steam pressure in the boiler is high, so as to make the water pump idle without water
