Description

Technical Field

[0001] The utility model relates to the technical field of milk processing equipment, in particular to a preheating device for milk processing. Background Art

[0002] Milk is one of the oldest natural beverages, often called "white blood." Its importance to the human body is undeniable. As the name suggests, milk is squeezed from female cows. Different grades of milk are available in different countries. Milk is rich in minerals, including calcium, phosphorus, iron, zinc, copper, manganese, and molybdenum. Most importantly, it is the best source of calcium for the human body, with an ideal calcium-to-phosphorus ratio, facilitating calcium absorption. Milk is a complex food, with at least 100 different types, primarily composed of water, fat, phospholipids, protein, lactose, and inorganic salts. During processing, fresh milk, after cooling and filtration, needs to be preheated to achieve homogenization.

[0003] The existing patent (Announcement No.: CN216533583U) discloses a preheating device for milk processing, which first drives the slider to move through a driving mechanism, and under the cooperation of the spring, can drive the slider to move left and right, thereby driving the annular heating tube to move left and right, so that the inside of the preheating box can be heated evenly. The motor can drive the hollow shaft to rotate, and the water can be pumped into the hollow shaft through the water pump, and sprayed onto the inner wall of the preheating box through the nozzle, so as to facilitate the removal of milk remaining on the inner wall of the preheating box.

[0004] However, the existing equipment still has certain shortcomings. When the annular heating tube of the equipment moves, the outer wall of the preheating box is exposed, which will cause a large amount of heat loss, reduce heating efficiency, increase energy costs, and is not conducive to the economic benefits and sustainable development of the enterprise. In addition, the parts inside the heating tank need to be regularly inspected and troubleshooted after a period of use, but the closed tank body is not convenient for the inspection and maintenance of the internal parts of the tank body. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a preheating device for milk processing to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a preheating device for milk processing, comprising a heating tank body, a cavity being provided inside the heating tank body, a first connecting ring being rotatably installed in the cavity, an empty groove being provided on the outer wall of the heating tank body near the top position, a plurality of groups of heating blocks being fixedly installed on the lower surface of the first connecting ring in an array of equal angles around the center of a circle, a second connecting ring being fixedly installed on the lower surface of the heating block, a first motor being fixedly installed on the outer wall of the heating tank body below the empty groove by bolts, a gear being fixedly sleeved on the outer wall of the output shaft of the first motor, a tooth groove being provided on the outer wall of the first connecting ring, and the tooth groove being meshed with the gear.

[0014] Furthermore, two groups of L-rods are symmetrically fixedly connected to the upper surface of the top cover, and a card rod is slidably sleeved on the inner wall of the L-rod. The bottom end of the card rod extends to the inside of the top cover, and a through hole of matching shape and size is opened at the contact position between the top cover and the card rod.

[0015] By adopting the above technical solution, corresponding rectangular through holes and perforations are opened at the contact positions of the two groups of L rods and the top cover with the card rod, which can limit the card rod while moving up and down to prevent it from rotating and increase the fixing strength of the equipment.
