Milk Beverage Processing Line

Milk Beverage Processing Line Description

Milk-containing beverages or milk-based products are beverage products prepared or fermented with dairy products or raw milk as raw materials, adding water and appropriate amounts of auxiliary materials, after sterilizing, homogenizing and then filling into small packages.

According to customer needs, we can design formulate milk-containing beverages, fermented milk-containing beverages, lactic acid bacteria beverages or milk-flavored beverages.

The capacity of the milk beverage processing line is available for customers to choose from 1T/H-20T/H, and the final product can be packed into cartons, PET bottles or glass bottles.

The entire production line is equipped with a CIP cleaning system to clean equipment, pipelines and storage tanks to ensure the sanitary conditions of the production line, thereby producing high-quality products.

The milk beverage processing line is composed of raw milk acceptance system, blending system, sterilization system, fermentation system, filling system and packaging system, CIP system, RO pure water system, boiler, ice water unit and other equipment.

The raw materials in milk beverages are raw milk or milk powder, pure water, sugar, sweeteners, thickeners, cocoa powder, sour agents, emulsifiers, flavors and pigments.

Common flavored milk beverages include strawberry, banana, pineapple, apple, coffee or chocolate flavors.

Classification and End Package of Milk Beverage Processing Line

Milk beverages can be filled into small containers like bottles, tin cans, pouches or cartons with the 100ml-2500ml package. According to ingredients adding, they can be divided into the following four styles:

Flavored milk beverages

Using sugar and (or) sweeteners, sour agents, milk or dairy products, fruit juices, food flavors, tea or plant extracts, etc., all or part of them as raw materials, the formulated milk protein content cannot reach The basic technical requirements for formulated milk-containing beverages [milk protein content (mass fraction) ≥ 1.0%], or the fermented milk protein content does not meet the basic technical requirements for lactic acid bacteria beverages [milk protein content (mass fraction) ≥ 0.7% Drinks.

Blended milk beverages

A beverage prepared from raw milk or dairy products, adding water, sugar and (or) sweeteners, sour agents, fruit juice, tea, coffee, plant extracts, etc. Then after sterilizing and then filling into bottles or tetra pak cartons. Milk protein content (g/kg)≥1.0.

Fermented milk beverages

It is a beverage that uses milk or dairy products as raw materials, lactic acid bacteria and other beneficial bacteria are cultured and fermented into the emulsion, then blended and prepared by adding water, sugar and (or) sweeteners, sour agents, juice, tea, coffee, plant extracts, etc., such as lactic acid bacteria milk beverages. According to whether it has been sterilized or not, it is divided into the sterilized (non-viable) type and non-sterilized (viable) type. Fermented milk-containing beverages can also be called yogurt (milk) beverages. Milk protein content≥1.0; Benzoic acid/(g/kg)≤0.03.

Lactobacillus beverage

Milk or dairy products are used as raw materials, and water is added to the emulsion prepared by lactic acid bacteria fermentation, and one or more of sugar and (or) sweeteners, sour agents, fruit juices, tea, coffee, plant extracts, etc. are added. The finished beverages are classified into sterilized (non-viable bacteria) type and non-sterilized (live bacteria) type according to whether they have been sterilized.

Milk protein content/% (mass fraction) ≥0.7; non-sterilized (live bacteria) type, lactic acid bacteria live bacteria index ≥1×10^6CFU/mL at the factory; sales period shall be carried out according to the number of live lactic acid bacteria marked on the product label.

Technological Flowchart of Milk Beverage Processing Line

Mixed milk beverages processing flowchart

Mixed milk beverages are made from raw milk or milk powder, then adding lactic acid or citric acid, syrup, stabilizers, flavors, pigments, vitamins or minerals, after blending with these ingredients, milk beverage is obtained, then the milk beverage will go for homogenizing, degassing and sterilizing. Then the sterilized milk beverage is filled into small bottles or tinplate cans, after filling, the packaging container is sterilized for a second time through a retort or pasteurization tunnel, and then cooled to room temperature and finally packaged in a carton or film shrink package. However, if aseptic cartons or pouches are used for filling, no secondary sterilization equipment is required.

There are two methods for processing fermented milk beverages: the first method is after the raw milk is accepted and fermented firstly, then fruit and vegetable juice, sugar, stabilizers, flavors, pigments and other auxiliary materials are added, after mixing with all ingredients, then homogenizing, sterilizing and filling into consumable packages; The second type is to formulate first, then ferment, which is to mix all the raw materials together according to the formula, after co-fermentation, and then mix by adding sugar, stabilizers, spices, etc., to homogenize the beverage.
