Solid Yogurt Block Food Freeze Dryer

The food freeze-drying machine prepares the active solid yogurt block stored at room temperature to solve the problems of high energy consumption, inconvenience to carry, and short shelf life for the cold chain storage and transportation of active bacterial yogurt. The solid yogurt block prepared by freeze-drying can reduce the loss of nutrients and flavor of the yogurt during the freeze-drying process, and has good quality and good storage stability.

Using mixed strains (Streptococcus thermophilus: Bacillus bulgaricus is 4:1) to ferment yogurt, the lactic acid bacteria content in the finished yogurt is about 4.8*108cfu/g. The actual listening results show that: The order of the effect of program freeze-drying process parameters on the quality of viable room temperature solid yogurt is: first-stage freezing time > first-stage freezing temperature > second-stage freezing time > second-stage freezing temperature > fourth-stage freezing temperature Stage freezing time/temperature > 3rd stage freezing time/temperature = pre-freezing time/temperature. The vacuum freeze-drying conditions for the obtained yogurt are: -45°C/2h (pre-freezing) - -30°C/12h - 0°C/3h - 10°C/5h - 35°C/5h, and the environmental vacuum degree during the freeze-drying process is controlled to be 1Pa. Under this condition, the lyophilized yield of yogurt was 25%, the water activity Aw of the dried yogurt product was 0.47, and the number of live lactic acid bacteria reached 2.0x107cfu/g ~ 1.0x108cfu/g.
