Description

Technical Field

[0001] This utility model relates to the field of pet freeze-dried product technology, and in particular to a cooling circulating water supply device for pet freeze-dried product production. Background Technology

[0002] Freeze-dried pet food is a type of food produced using vacuum freeze-drying technology, primarily used in pet food. The process involves freezing fresh meat at extremely low temperatures and then sublimating the ice directly into water vapor in a vacuum environment, thus removing moisture. This technology not only preserves the nutrients and flavor of the ingredients but also maintains the integrity of their cellular structure, allowing for long-term preservation even without preservatives or additives. The production process of freeze-dried food includes two main steps: freezing and vacuum drying. First, the food is frozen at extremely low temperatures, and then the ice is sublimated directly into water vapor in a vacuum environment. This process is typically repeated twice, followed by sterilization. To prevent drastic temperature changes during processing that could cause nutrient loss or damage, a transfer rack is used for pre-freezing the food during freeze-drying. However, existing transfer racks for freeze-drying pet food are mostly simple in structure, only providing placement capacity and not pre-cooling capabilities. Therefore, we propose a cooling circulating water supply device for freeze-drying pet food production. Utility Model Content

Multiple sets of mounting blocks 8 are installed below the transfer frame 1. The mounting ends of the mounting blocks 8 are fixedly connected to the transfer frame 1. The mounting corners of the cooling water tank 42 are installed corresponding to the mounting blocks 8 and are fixedly connected to the mounting blocks 8. The multiple sets of mounting blocks 8 can make the cooling water tank 42... When installed, it is more stable. The outlet of the water pump 41 is connected to a cooling water pipe 43. One end of the cooling water pipe 43 is installed corresponding to the outlet of the water pump 41 and is fixedly connected to the outlet of the water pump 41. The cooling water pipe 43 allows the coolant drawn from the cooling water tank 42 by the water pump 41 to circulate. The cooling water pipe 43 is laid in a loop shape along the two sets of placement racks 2. The loop shape of the cooling water pipe 43 along the placement racks 2 can quickly cool down the pet freeze-dried food placed on the multiple placement plates 7 on the placement racks 2.

The mounting end of the positioning rod 5 is installed corresponding to the placement rack 2 and is fixedly connected to the placement rack 2. Each set Multiple positioning holes 9 are provided on each positioning rod 5.

[0023] In this embodiment, the operator places the food on the placement plate 7, and then assembles the placement plate 7 into the corresponding groove 6 on the placement rack 2. After the placement plate 7 is placed, the operator powers on the water pump 41, heat exchanger 44, and cooling tower 45. The water pump 41 draws coolant from the cooling water tank 42 and then circulates the coolant through the cooling water pipe 43. The coolant in the cooling water pipe 43 quickly absorbs the heat from the food on the placement plate 7 during circulation. After absorbing heat, the coolant in the cooling water pipe 43 is transported to the heat exchanger 44. The coolant is then transported to the cooling tower 45 for heat exchange treatment.
