Detailed Description
Example 1
The raw milk is preheated to 60 ℃ and passes through the separator 2, and the rotating speed of the separator 2 is 7500r/min. The separator 2 is provided with 108 discs, the milk passes through each disc layer by layer to be separated, impurities are naturally deposited in the rapid flow of the milk, the fat gradually flows upwards to form layers, 2 different pipelines are formed at an outlet section of the separator 2, namely the forming mode of skim milk and cream (fat), and the separated impurities are discharged at a slag discharge port at the lowest end.
The separated fat, the cream and the skim milk jointly flow to the homogenizer through two pipelines, the fat in the cream pipeline can generate turbulent vortex flow under high-speed flow, the flow rate is 15 tons per hour, shearing, impacting and cavitation effects can be generated when the fat passes through the high-pressure homogenizing valve 32, namely the reciprocating plunger 3212 pumps the fat into a narrow gap, the fat is extruded by a very high pressure (200 bar) in the gap, and the fat only bears a very low pressure after passing through the gap, so the fat which loses pressure instantly can generate a very large explosive force; the fat with instant pressure loss can be sprayed out at a very high speed, the spraying speed is 200-1000 m/s, and strong impact force can be generated; certain shearing force can be generated among fat particles in the high-speed spraying process of fat; the effects of fat breaking, homogenizing, crushing and emulsifying can be achieved well through the explosive force, the impact force and the shearing force, and the homogenized fat is mixed with the skim milk, so that the milk is smaller in fat particles and more dense. Because partial homogenization is just to homogenize fat, the homogenization effect is better and more targeted, and the absorption of the human body to the fat can reach a higher level.
The homogenized milk has a more stable state when the yogurt is fermented, fat in the milk is more dense after being homogenized and is more stable, if the homogenization effect of the yogurt is not good during fermentation, the fat floats upwards, the solidified yogurt has prominent performance, a thicker milk skin is formed on the upper layer of the product after the yogurt is fermented without homogenization or the homogenization does not reach the standard, the milk skin is the fat floating phenomenon caused by the unsatisfactory homogenization effect, and the fat floating can influence the sense and flavor of the product.
