The first embodiment is as follows:

a milk preheating mechanism comprising:

the preheating device comprises a preheating tank 1, wherein a water storage cavity 12 is arranged in the preheating tank 1, the preheating tank 1 is provided with an inner wall 13 and an outer wall 14, and an interlayer 15 is enclosed between the inner wall 13 and the outer wall 14;

coil pipe 2, including inner tube 21 and outer tube 22, outer tube 22 cover is established in the outside of inner tube 21, the left end of inner tube 21 is feed end 211 and the right-hand member is discharge end 212, the right-hand member of outer tube 22 is intake end 221 and the left end is for going out water end 222, the intake end 221 and the water storage chamber 12 intercommunication of outer tube 22, coil pipe 2 is around establishing in intermediate layer 15.

Specifically, when milk is preheated, hot water is stored in the water storage chamber 12, the milk flows into the inner tube 21 from the feeding end 211 of the inner tube 21 and flows toward the discharging end 212, and the hot water in the water storage chamber 12 flows into the water inlet end 221 of the outer tube 22, flows between the outer tube 22 and the inner tube 21, exchanges heat with the milk in the inner tube 21, thereby heating the milk, since the discharge end 212 of the inner tube 21 corresponds to the water inlet end 221 of the outer tube 22, and the flowing direction of the milk and the hot water is opposite, the hot water which is heat exchanged with the milk and is close to the discharge end 212 is just entering between the outer tube 22 and the inner tube 21 from the water storage cavity 12, the temperature is the highest, the milk which is closer to the feed end 211, because the milk in the front-section pipeline exchanges heat with the hot water, the more the temperature loss of the hot water exchanged with the milk is, the lower the temperature is, the milk is gradually heated by the hot water, and finally the milk at the discharge end 212 reaches the preheating temperature; because the milk continuously flows along the coil pipe 2 coiled in the interlayer 15, compared with the milk directly heated in the tank body, the milk heating tank has more uniform heating effect and avoids the problems of caking and the like; the coil pipe 2 is coiled in the interlayer 15 to ensure that the coil pipe has enough length for milk and hot water to flow, the outer wall 14 reduces the loss of hot water temperature in the coil pipe 2, the inner wall 13 and the interlayer 15 reduce the loss of hot water temperature in the water storage cavity 12, and the preheating efficiency is improved.

Example two:

the difference between the second embodiment and the first embodiment is that the feed end 211 is connected with a filtration feed pump 31.
