Embodiment 1

[0026] like figure 1 As shown, the present invention discloses a formula-type multifunctional liquid milk production method, which comprises the following steps:

[0027] S0: Pasteurize the raw milk. During the sterilization process, the heating temperature is above 50°C, and the heating time is 30 to 40 minutes. Sterilization treatment is carried out from the beginning of raw milk processing to ensure the hygiene of the milk source for subsequent processing, and at the same time to avoid bacteria and other residues in equipment or pipelines.

[0028] S1: Skim the sterilized raw milk by a skim separator to obtain skim milk and a fat standard solution. Fat standards can be temporarily stored in special containers for later use.

[0029] S2: Select microfiltration membrane or ultrafiltration membrane for dialysis treatment of skim milk, preferably ultrafiltration membrane, and obtain protein standard solution (ultrafiltration concentrate) and first dialysate through dialysis t...

Embodiment 2

[0035] The difference between this embodiment and the first embodiment is that step S0 is removed, the raw milk is directly skimmed first, the obtained skim milk is pasteurized first (ie, step S11 ), and the sterilized skim milk is then processed in step S2 . In step S11, the heating temperature is above 50°C, and the heating time is 30-40 min.

[0036] In the following, description will be given by formulating three different formulas, which are high-protein formula, lactose-free formula and high-protein yogurt. The contents of each component in the fat standard solution, protein standard solution, lactose standard solution and total solid standard solution obtained from the raw milk through the above steps are shown in Table 1 and Table 2. The composition requirements of high-protein formula milk and lactose-free formula milk, as well as the mixing ratio of fat standard solution, protein standard solution, lactose standard solution and total solid standard solution are show...

Abstract

The invention relates to a formula type multifunctional liquid milk production method which comprises the following steps: S1, degreasing raw milk to obtain skimmed milk and fat standard liquid; s2, dialyzing the skimmed milk to obtain a protein standard solution and a first dialysate; and S3, performing dialysis treatment on the first dialysate to obtain a lactose standard solution and a second dialysate. S4, performing reverse osmosis purification treatment on the second dialysate to obtain total solid standard liquid and recycled water; wherein the total solid standard liquid is an aqueous solution containing mineral substances. And S5, mixing the fat standard liquid, the protein standard liquid, the lactose standard liquid, the total solid standard liquid and the recycled water according to the formula proportion to obtain the required formula milk. According to the invention, various formula milk with different functions can be blended on one production line, the switching is flexible and convenient, in addition, the equipment redundancy can be effectively saved, the simplification of the equipment and the control of the production cost are facilitated, the occupied space is smaller, and the centralized management is facilitated.

Description

technical field [0001] The invention relates to the technical field of dairy product production, in particular to a formula-type multifunctional liquid milk production method. Background technique [0002] Conventionally produced liquid milk is divided into pasteurized milk and sterilized milk. Among them, the production process of pasteurized milk is: raw milk acceptance-purified milk-refrigeration-standardization-average-pasteurization-cooling-filling-refrigeration. The production process of sterilized milk is acceptance of raw milk-clean milk-refrigeration-standardization-preheating-average-ultra-high temperature instantaneous sterilization (or sterilization)-cooling-filling-finished product storage. On this basis, according to the needs of different consumers, formula milk with different formulas needs to be produced, such as skimmed milk, which requires the addition of skim milk pasteurizers and skim milk separators; low-lactose or lactose-free milk needs to add lactas...
