Yogurt Production Line | Yogurt Machine

Shuliy yogurt production line is composed of the professional milk processing equipment for making plain and flavored yogurt, which is specially designed for most yogurt producers with different yogurt production scales. Our commonly sold yogurt production lines are the 200L/300L/500L/1000L yogurt processing plants. These yogurt machines have low prices and high efficiency so that they are always applied in beverage stores, dairy processing plants, snack shops, pastures, cake houses, and other fields.

Yogurt process flow of the commercial yogurt makers

  • Fresh milk as raw materials:

Fresh milk cold-storage(about 4℃ keeping)——Milk filtering(removing impurities)——Milk preheating(about 45℃)——Milk homogenizing(55-70℃/20-25MPa)——Milk sterilizing(pasteurization or high temperature sterilization)——Sterilized milk cooling(43-45℃)——Adding related bacteria species and additives ——Yogurt fermenting(needs about 6-8 hours)

  • Milk powder as raw materials:

Milk powder mixing and preheating with water——High-speed fine mixing——Milk preheating——Milk homogenizing(55-70℃/20-25MPa)——Milk sterilizing(pasteurization or high-temperature sterilization)——Sterilized milk cooling(43-45℃)——Adding related bacteria species——Yogurt fermenting(needs about 6-8 hours)

Detailed components of the automatic yogurt production line

The whole set of yogurt processing line is mainly composed of a series of yogurt production tanks which are connected by the stainless pipes and adjustable pumps. No matter what the customers’ yogurt production requirements are, we can collocate the most suitable machines and customize the production lines for them. The hot-sale daily yogurt processing yields with Shuliy yogurt maker machines are 200L/D, 300L/D and 500L/D.

  • Cold-storing of milk

The fresh milk collected from pastures should be refrigerated in a timely manner. The low-temperature refrigerated tank is equipped with a special compressor, which can provide fresh milk with a fresh temperature of about 4℃, which can ensure that the milk does not deteriorate for a long time.

  • Milk filtering for removing impurities

The dedicated double-layer filter or single-layer filter can effectively filter out impurities in milk. The three-dimensional screen device in the filter can quickly remove impurities such as hair or other residues in the milk.

  • Milk preheating with 45℃

The preheating tank is designed with the jacket-structure where can be injected water for heating the inner milk. The heating method adopts electric heating. Inside of the milk preheating tank, there is a mixer shaft for mixing the milk when preheating, which can make sure that the milk is preheated evenly. After preheating, the milk temperature is about 45℃.

  • Milk homogenizing

The preheated milk will be extracted into the milk homogenizer for further processing. Under the processing conditions of 50-70℃ in temperature and 20-25MPa in pressure, the macromolecular and fat balls will be refined into small particles, which can ensure the good tastes of the final yogurt.

  • Milk sterilizing and cooling

The sterilization tank also has the double-layer structure which can heat the water with high temperature for milk sterilizing. This milk sterilizing link is very important for killing most of the bacteria in the milk and ensure the final yogurt quality. The whole milk sterilizing process will last about 40 minutes. When the milk temperature reaches about 85℃, the milk sterilization will be finished. Then we discharge the hot water and inject the cold water(with room temperature) for cooling.

  • Adding bacterial species and additives

When the milk temperature cooling down(about 43-45℃), we can add the related bacterial species and the additives. The users can add these materials based on their own yogurt processing recipes or their requirements for the flavored yogurt production.

  • Yogurt fermentation

The last step for making yogurt is fermenting the milk for about 6-8 hours. The yogurt fermenting temperature is about 45℃. And during the fermentation process, there will occur the lactic acid bacteria that are good for the human body.

  • Automatic yogurt packaging

After the yogurt fermentation is finished, we can use the automatic filling and packing machine to dispense the yogurt into cups, or bottles. The yogurt filling machine has the multifunctions for filling yogurt into cups or bottles quantitatively and automatic putting bottle caps or sealing. After packaging, these yogurt products can be sold to the market.

  • Automatic cleaning system for yogurt machines

This cleaning system also named the CIP washing system, which is composed of three stainless-steel tanks. These tanks are separately filled with clean water, acid water, and alkali water, which can clean the whole yogurt production line deeply within only several minutes.
