Description

Fully enclosed steam direct heating continuous sterilizer

Technical field:

The utility model relates to a continuous high-temperature sterilizing and cooling bottle cleaning machine suitable for industries such as canned food and beer.

Background technique:

At present, manufacturing industries such as canned food and beer use steam to directly heat and sterilize, which cannot solve the contradiction of closed and continuous operation. Only steam sterilization can be performed in non-continuous operation, and continuous operation is not directly sterilized by steam. There is also the use of water for sterilization. The sterilization section of this type of continuous sterilizer is a large water tank. There is a steam diffuser pipe at the bottom of the tank. The steam emitted by the steam diffuser heats the water body, and the water body then transfers heat to the sterilized object, and the water body is polluted. Finally, new water needs to be replaced, and the sewage with sterilizing temperature will be released, which consumes a lot of water, high energy consumption and time-consuming. The cooling section of the continuous sterilizer is also a large water tank, which is connected to the end of the sterilization section. The water tank is filled with cold water, and the sterilized cans are cooled in the cold water.

Invention content:

The utility model aims at the deficiencies of the prior art, and provides a fully enclosed steam direct heating continuous sterilizer which can realize continuous operation, save water, save energy and have high efficiency.

The technical solution of the utility model is: a fully enclosed steam direct heating continuous sterilizer, which is characterized in that: a conveyor belt 1 is provided, a steam cover 2 is provided on the conveyor belt 1, and a steam shield 11 is provided on the bottom of the steam cover 2 , steam hood 2 is provided with steam pipe 3 and steam pipe 4; both sides of steam hood 2 are respectively provided with low concave water tank 5, conveyor belt 1 passes through water tank 5, steam shield 11 extends into water tank 5, water tank 5 The bottom is provided with diffuser pipe 4.

The rear section of the conveyor belt 1 is provided with a cooling clean bottle cover 6, which is located outside the rear top of the water tank 5 on the rear side of the steam cover 2. The cooling clean bottle cover 6 is also provided with an air duct 16 and a spray pipe 15, wherein the air duct 16 is connected with blower fan 7.

The bottom of the cooling clean bottle cover 6 is provided with a recovery water tank 12, and the recovery water tank 12 is connected with the spray pipe 15 through the water pump 8.

The inlet and outlet of the sterilizing steam hood of the utility model use water body as the steam-blocking medium to block the outflow of steam and stabilize the sterilizing temperature in the steam hood. At the same time, the packaging bottle (can) can freely pass through the water body with the conveyor belt to realize continuous operation. When the sterilizing steam pressure exceeds the pressure corresponding to the set steam temperature, the steam will release steam through the water to relieve the pressure; the deeper the steam baffle is inserted into the water, the greater the controllable pressure of the steam hood and the higher the temperature inside the hood. In addition, this equipment can also complete the preheating, cooling, and bottle cleaning processes, so that the temperature change of the sterilized material is in a natural transition, without frying the bottle, safe in operation, and one machine with multiple functions.

Detailed ways:

The specific embodiment of the utility model will be described below in conjunction with the accompanying drawings. As shown in Figures 1 and 2: a fully enclosed steam direct heating continuous sterilizer is equipped with a circular hollow conveyor belt 1, which is positioned by a forward guide rail 9 and a reverse guide rail 13, and is driven by two synchronous drive shafts 10, The conveyor belt 1 is provided with a steam hood 2, the bottom of the steam hood 2 is provided with a steam shield 11, and the bottom of the conveyor belt 1 in the steam hood 2 is provided with a steam vent pipe 3 and a steam diffuser pipe 4, and the lower part of the steam diffuser pipe 4 is evenly distributed. There are a large number of steam vents, and the steam emitted by the steam vents passes through the conveyor belt 1 and is evenly distributed in the entire steam hood. Both sides of the steam cover 2 are respectively provided with a low-concave water tank 5, the bottom of the water tank 5 is preferably arc-shaped, the steam shield 11 extends into the water tank 5, the conveyor belt 1 passes through the water tank 5, and the shape of the conveyor belt 1 in the water tank 5 is: Approximate bow shape, preferably further positioning with a pressing plate; the bottom of the water tank 5 is provided with a diffuser pipe 4.

The rear section of the conveyor belt 1 is provided with a cooling clean bottle cover 6, which is located outside the rear upper part of the water tank 5 on the rear side of the steam cover 2. The cooling clean bottle cover 6 is also provided with an air duct 16 and a spray pipe 15, wherein the air duct 16 is connected with blower fan 7. The bottom of the cooling clean bottle cover 6 is preferably provided with a recovery water tank 12, and the recovery water tank 12 is connected with the spray pipe 15 by the water pump 8. The water in the recovery water tank 12 is used for cooling the clean bottle and can be recycled. The rear of spray pipe 15 preferably arranges secondary spray pipe 17, and it directly joins with running water pipe 18, further cools clean bottle.

work process:

First, the steam generating device feeds high-temperature steam into the water tank 5 and the steam hood 2 through the steam pipe 3 and the steam diffuser 4, so that the water temperature in the water tank 5 rises and the steam hood 2 is filled with steam; the conveyor belt 1 is started, and it drives The packaging bottle enters the first water tank to preheat to prevent bottle explosion, then enters the steam hood 2 for sterilization, then enters the second water tank for precooling, and finally enters the cooling clean bottle cover 6, and passes in cold air and cold water. Complete the cooling and bottle cleaning process.
