Description

Technical Field

[0001] The utility model relates to the technical field of milk powder production equipment, in particular to a milk powder concentrating device. Background Art

[0002] When producing milk powder, it is necessary to carry out concentration treatment in order to remove part of the water in the milk, increase the concentration of milk solids, and reduce the drying time and energy consumption. Generally, the vacuum concentration method is used to concentrate the raw milk to about 1 / 4 of the original amount. After that, spray drying is carried out to spray the concentrated milk into fine droplets, which come into contact with high-temperature air to quickly evaporate the water and form dry powder. Generally, equipment such as spray towers or centrifugal sprayers are used, and the temperature is between 130 and 160°C.

[0003] Vacuum concentration is a method of concentrating a solution by using vacuum to lower the boiling point of the solvent and accelerate the evaporation of the solvent. Since the boiling point of the solvent is lowered under vacuum, high-temperature heating is not required, which can save a lot of energy consumption. Since the evaporation rate of the solvent is accelerated under vacuum, the concentration time can be shortened and production efficiency can be improved.

[0004] In the prior art, a Chinese patent document with the authorization announcement number CN215841646U records a PCBA board cutting device. The patent allows milk to enter the interior of the tank through the feed port and be heated by the heater. The milk at the bottom of the tank will be heated first, and then the suction pump will work to suck through the tube disc at the bottom. Under the suction of the tube disc, the milk at the bottom is transported to the tube disc at the top through the connecting pipe for spraying, so that the milk at the bottom of the tank moves to the top, thereby transferring heat and accelerating the heating efficiency of the milk.

[0005] The prior art does not have a sterilization function, and the contents inside the concentration tank are prone to breed bacteria, reducing the safety of food processing; moreover, it is not convenient to discharge the steam generated by heating, and some devices in the prior art discharge the steam through simple pipes, and the steam is prone to condense in advance at the position of the pipe, causing the condensed water to flow back into the concentration tank. For this reason, we propose a milk powder concentration device. Utility Model Content
