What is the commercial yogurt maker?

The commercial yogurt machine is the new-designed yogurt maker with the electric heating method, which can provide the appropriate fermentation conditions for the sterilized milk fermenting. The milk for making yogurt is mainly fresh milk, like goat milk, cow milk, and horse milk. Before milk fermentation, these fresh milk should be sterilized with the temperature of 85℃first to kill most of the bacteria of the milk. When the yogurt fermenting is finished, this yogurt maker will turn to the refrigerated storage temperature of about 4℃automatically.

Main structure of the yogurt fermentation machine

Seeing from the outside of this yogurt maker, it looks like a big cabinet with the transparent glass door and inner storage racks. Actually, this yogurt fermenter is an intelligent temperature control chamber for yogurt fermentation and cold keeping. It is composed of the compressor, exhaust fan, the radiator, digital display, sterilization lamp, temperature sensor, body casing, and universal wheels. The chamber is equipped with trays and grids for holding the separate yogurt cups. And for meeting different requirements of the customers about the yogurt production, this yogurt machine can be designed with the single-chamber type and the double-chamber type.

Main classifications of the yogurt maker

1. Single-chamber yogurt machine

This type of yogurt processing machine is very suitable for the small drink stores or the retail stores for providing fresh yogurts. It has one fermentation chamber and one glass door, and it’s the volume is about 176L and the yogurt yield is 50-100L per 8 hours. The body casing of this single-chamber yogurt maker is made of stainless steel so that it is resistant to wear and tear.

2. Double-chamber yogurt maker

The double-chamber yogurt fermenting machine is the commercial type of yogurt processing machine, which is suitable for various restaurants, bakeries, fast food shops, cafes and so on. It has two fermentation chambers so that its inner volume is larger than the single-chamber type of yogurt machine. Its plain yogurt yield in 8 hours is about 150L. It is also made of the durable stainless steel and easy to move with the universal wheels.

How the delicious yogurt is made by the yogurt fermenting machine?

  1. The fresh milk should be sterilized first with the special sterilization equipment with a temperature of 85℃ for about 10 minutes. Then when the temperature cooling down to 45℃, pour about a pound of the yogurt fermenting strains into the container and mix well, then pour into a stirred tank, stir for 3 minutes, and let stand for 5-10 minutes.
  2. Dispense the milk from the mixing tank into dedicated small yogurt placing cups and drain the cups into the tray on the yogurt machine grid.
  3. Start the yogurt maker and set the yogurt fermentation temperature with 42℃-43℃. Notes: Before using the yogurt machine, the yogurt machine’s console should be spray-sterilized with 75% concentration of medical alcohol (if the bacteria is contaminated, the quality of the yogurt will be bad). After the alcohol spray, open the door for about 2-3 minutes to remove the alcohol smell and then sterilize the sterilization lamp (the sterilization time is set at the factory).
  4. After 8 hours of yogurt fermentation, this yogurt maker will switch to low temperature keeping automatically.

Precautions of the yogurt processing with the electric yogurt machine

  1. In order to protect the compressor, the compressor can be restarted after being stopped for 3 minutes under any working condition.
  2. When it is detected that the temperature sensor has an open circuit or short circuit fault for 3 seconds, it should stop automatically (open circuit fault flashes E4LL, short circuit fault flashes E4HH). The current working status indicator flashes and the buzzer will beep.
  3. The density of fresh milk is close to that of specific heat and water, which is nearly a thousand times that of heating the carrier air. Therefore, if you want to quickly heat the milk or quickly cool the yogurt, you must ensure that the air in the box is smooth. For this reason, the milk cup must not be placed too densely, and the pile is too high, and there must be enough clearance between the cups.
