Description

Technical Field

[0001] This utility model relates to the field of milk pretreatment production technology, specifically to a feeding tank internal and external circulation refrigeration unit. Background Technology

[0002] Existing ultra-high temperature feeding tanks used for storing milk cannot effectively cool down the milk due to factors such as product ingredient preparation and storage time, which increases the risk of quality problems during milk storage.

[0003] When the milk temperature exceeds 7°C, it can only be transferred to other storage tanks by manually connecting a hose and cooling down during the secondary seasoning process. This increases the product loss of the seasoning process and cannot control the online cooling temperature. It is necessary to repeat the seasoning process repeatedly to achieve the required milk temperature.

[0004] This process reduces the utilization rate of the milk preparation pipeline, leading to a decrease in overall production efficiency. Simultaneously, cleaning the equipment and pipelines increases the consumption of renewable water, as well as the energy costs associated with electricity, alkali solutions, and acid solutions.

[0005] Therefore, there is an urgent need to propose a cooling unit with internal and external circulation in the feeding tank to solve the problems of low production efficiency and high energy consumption in the existing technology. Utility Model Content

[0006] In view of the above facts, in order to solve the problems of low production efficiency and high energy consumption in the prior art, this utility model designs an internal and external circulation refrigeration unit for the feeding tank.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A feeding tank internal and external circulation refrigeration unit includes a CIP cleaning station cleaning fluid outlet, a first milk mixing line, a second milk mixing line, a cleaning distribution plate interface, a refrigeration cooling plate heat exchanger, a refrigeration ice water outlet, a refrigeration ice water inlet, a feeding tank, a CIP cleaning station cleaning fluid inlet, and a connecting device.

[0009] The material enters the feed tank from the first and second milk mixing lines, and then enters the connecting device from the feed tank's outlet.

[0010] The cooling plate heat exchanger discharge butterfly valve is connected to the feed tank via a connecting device. The cooling plate heat exchanger is connected to the cooling plate heat exchanger discharge butterfly valve. The chilled water inlet is connected to the inlet of the cooling plate heat exchanger, and the chilled water outlet is connected to the outlet of the cooling plate heat exchanger.

[0011] The cleaning fluid inlet of the CIP cleaning station is connected to the cooling outlet butterfly valve of the refrigeration plate heat exchanger via a connecting device. The first cleaning pipeline is connected in sequence to the refrigeration plate heat exchanger, the material butterfly valve of the second tank area, the cleaning return butterfly valve of the second tank area, and the cleaning fluid outlet of the CIP cleaning station.

[0012] The cleaning fluid inlet of the CIP cleaning station is connected to the cleaning distribution panel interface via a connecting device. The second cleaning pipeline is sequentially connected to the feeding tank, the automatic discharge control valve, the manual discharge butterfly valve of the second tank area, the manual return butterfly valve of the second tank area, the material pump of the second tank area, the cleaning return butterfly valve of the second tank area, and the cleaning fluid outlet of the CIP cleaning station.

[0013] The push-button switch is located on the connecting device. The left side controls the material butterfly valve of the first tank area and the cooling discharge butterfly valve of the refrigeration plate heat exchanger, while the right side controls the cooling discharge butterfly valve of the refrigeration plate heat exchanger, the material butterfly valve of the second tank area, and the material pump of the second tank area.

[0014] Furthermore: the material enters from the first feeding tank area, which is connected in sequence to a refrigeration cooling plate heat exchanger and a refrigeration plate heat exchanger cooling discharge butterfly valve. The refrigeration plate heat exchanger cooling discharge butterfly valve is connected to the connecting pipeline of the first feeding tank area through a connecting device, and the material is discharged from the connecting pipeline of the first feeding tank area.

[0015] Furthermore: an ice water inlet control valve is provided between the chilled water inlet and the water inlet of the cooling heat exchanger;

[0016] A chilled water outlet control valve is installed between the chilled water outlet and the outlet of the cooling heat exchanger.

[0017] Furthermore: the process water inlets are respectively connected to the first sterilizer and the second sterilizer, and a process water pneumatic control butterfly valve is installed between the process water inlets and the first sterilizer and the second sterilizer.

[0018] Furthermore, a check valve is installed between the second tank area cleaning return butterfly valve and the cleaning fluid outlet of the CIP cleaning station.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model, through reasonable design and standardized installation, enhances the internal circulation cooling effect of ultra-high temperature milk storage tanks and the cooling effect of multiple milk storage tank areas, solves the cooling problem of milk storage tanks, makes the cooling efficiency more scientific and efficient, the cooling effect more ideal, and reduces the quality risks of milk storage.

[0021] 2. When the milk temperature exceeds 7°C, there is no need to manually connect a hose to the milk conditioning line for cooling and temperature reduction, which improves the utilization rate of the milk pretreatment equipment, enhances the overall production efficiency, and thus improves the overall production effectiveness.

[0022] 3. This utility model reduces the amount of waste generated during the milk processing and the frequency of cleaning the milk pretreatment equipment pipelines, avoids the waste of renewable resources such as cleaning water for equipment pipelines, and reduces the energy consumption of cleaning solutions such as electricity, alkali, and acid.

[0023] 4. This utility model realizes automated control, reduces the labor intensity of personnel, and at the same time reduces the failure rate and maintenance rate of equipment, reducing maintenance costs. Technicians can connect the pipelines of the source tank and the target tank to be cooled separately, and realize one-button control through the control button, ensuring the safety of personnel operation.
