Description

A pet dairy food milk tank temperature control system

Technical areas:

The utility model relates to the technical field of milk tank temperature control, in particular to a pet dairy food milk tank temperature control system.

Background technique:

With the development and changes of society, the companionship of pets has become more and more important in people's lives. Therefore, in addition to the staple food for pets, such as dog food, cat food, etc., there are also some pet snacks specially developed for pets. In addition to belly wrap, there are also some additives that play special roles such as softening hair, brightening hair, etc.

There is an existing pet milk snack. The production process is roughly as follows: fresh milk that has passed the inspection is sent into the first milk tank through a pipeline, and nutrients and ingredients are added. The milk tank has its own stirring device, and is sterilized by raising the temperature to 95° with steam. After 5 minutes, it is The homogenizer homogenizes the ingredients, mixes them evenly, and sends them to the second milk tank for temporary storage. At this time, the temperature naturally drops to about 75°. During this period, the second batching or further cooling is performed. The ingredients are also heated using steam, and through cooling The water is circulated to cool down, and then sent to a cold storage tank to prevent deterioration at 2-10°C. Finally, a packaging machine is used to fill the product for sale.

In the above process, the temperature of fresh milk in the first milk tank or the second milk tank is heated or cooled respectively by using high-temperature steam and cooling circulating water to enter the interlayer of the milk tank for heat exchange. During this period, the temperature is stable at a certain value. , what is needed is to introduce different amounts of steam and cooling water at the same time. This process is accomplished by manually observing the thermometer and manually controlling the opening and closing of the two pipeline valves. However, once the boiler air supply is unstable, the steam inlet temperature will fluctuate. Sometimes, manual labor cannot detect it in time, and the cooling water valve is not adjusted in time, causing the temperature of the milk tank to fail to meet the process requirements, which will affect the quality of the milk.

The heat exchange between the steam in the first milk tank 7 or the second milk tank 14 and the cooling water can regulate the temperature of the milk tank. If there is more steam, the temperature will be higher. If there is more cooling water, the temperature will be lower.

After the first drainage electric control valve 13 is opened, the cooling water or steam condensate after heat exchange in the interlayer of the first milk tank 7 enters the first drainage pipe 12 into the drainage main pipe 3 and is discharged;

After the second drainage electric control valve 20 is opened, the cooling water or the steam condensation water after heat exchange in the interlayer of the second milk tank 14 enters the second drainage pipe 19 into the drainage main pipe 3 and is discharged.

The thermostat 4 senses the temperature of the first milk tank 7 or the second milk tank 14 through its own sensor 25, and presets a temperature range value. When the temperature rises to within the range value, the thermostat 4 monitors the first milk tank 7 or the second milk tank 14. When the temperature of the second milk tank 14 is higher than the upper limit of the preset temperature range, the thermostat 4 controls the corresponding valve actions of the two milk tanks. The opening and closing degrees of the first milk tank 7 and the first steam electronic control valve 9 decrease. , the opening and closing degree of the first cooling water electronically controlled valve 11 increases, the cooling water is more, and the temperature decreases. The second milk tank 14 adjusts the temperature in the same way.

The steam can be passed from the steam discharge port 21 through the preheating pipe 5 into the second milk tank 14 to preheat the second milk tank 14 in advance, thereby reducing the amount of steam introduced into the second milk tank 14 during use.

Close the preheating inlet valve 23 and open the preheating outlet valve 22. The steam from the first milk tank 7 can be used as a heat exchange medium to pass into the heat exchanger 6, and the cooling water flowing in the first cooling water inlet pipe 10 will be slightly heated. , but there is still a temperature difference between the cooling water and the steam. The purpose of this is that the high-temperature steam is introduced from bottom to top, and the high temperature first exchanges heat with the lower part of the milk tank. The temperature of the rising steam is slightly reduced, and the cooling water is introduced from top to bottom. , the low-temperature cooling water first exchanges heat with the upper part of the milk tank, and the cooling water temperature decreases slightly. In this way, the temperature of the lower part of the milk tank is always higher, while the temperature of the upper part of the milk tank is always lower, which affects the overall temperature regulation of the milk tank. , especially when the cooling water first comes in, the temperature difference with the steam is large, and it is difficult for the upper part of the milk tank to maintain the temperature. Therefore, the heat exchanger 6 preheats the cooling water, which can reduce the temperature difference, so that the upper part of the milk tank can not only stabilize the temperature fluctuations, but also heat exchange and adjust temperature.

The above descriptions are only preferred embodiments of the present utility model and are not intended to limit the present utility model.
