Yogurt making applications
What are the 7 steps for making your own yogurt?
1. Mixing system
- Fresh milk or recombined milk is the basic ingredient, as well as adding sugar, stabilizer and other minor ingredients according to recipe to make yogurt.
- *Vacuum mixer (Powder/liquid high shear mixer)
- *Buffer tanks
- *Heating/cooling system
- *Key parameter: 95℃ for 300s
- *Plate heat exchanger used to improve heat exchanging efficiency
- *System design conform to EHEDG code
- *Hot products heat exchanged with cold products, heat recovery rate high up to 90%, steam consumption low down to 30kg/t milk, significantly reducing energy consumption and operation cost
- *Pressure difference design for Products/heating (cooling) medium, product/product to ensure Sterilized product pressure higher than none pasteurized product or medium, no product contamination risk
- *gentle heating technology, long continuous running time
- *Independent CIP circulation system maximize cleaning and energy consumption efficiency
3. Culture inline feeding system
Culture feed into base ingredients for fermentation, base ingredients flow through the culture tank bottom and top to involve culture, higher culture use ratio .
4. Fermentation system
- Fermentation system is the core of yoghurt process, the design will affect products quality and stability.
- *Fermentation tanks are ultra clean, mirror polished, 45ºcone bottom design make discharge and cleaning are easy.
- *Insulated tanks ensure proper fermentation process temperature.
- *Tanks with top mounted agitator, it runs when base ingredients feed into tanks, make sure culture are evenly distributed into base ingredients, it stops after feeding finish, and start again after fermentation for emulsion broken, but not destroy yoghurt viscosity.
- *Fermentation tanks equipped with aseptic breather valve and aseptic air system and litter positive pressure protection to avoid contamination.
- *It also equipped with aseptic sampling valves, it make it’s possible for aseptic sampling to check viable organism and physicochemical index.
- *Side feeding design to avoid air bubble.
- *Brown milk fermentation tanks jacketed for heating, after 95º brown stain, it cool down to 38º for fermentation.
- *Cheese fermentation tanks equipped with agitator scraper, it could scrape and collect products when discharge.
- *Automatic valves control, valve block discharge, double seat and double seal mixing-proof valves to avoid cross pollution of different pipe line.
5. Yoghurt cooling system
When the acid degree reach required point, yoghurt need to cool down to 15-20℃ immediately for fermentation ending, products cooled through special plate heat exchanger, in order to get uniform products, it’s better to empty all fermentation tanks in half hour, normally, the cooled yoghurt stored in buffer tanks for filling.
- *The product is stored in buffer tanks after culture feeding, when filler is ready, product heated to 42±2℃ through the inline heating system.
- *Hot water circulation system provide stable heating temperature, products heated before filling, when filler stops, the operator needs to push products out for pipe line only, buffer tank product will not be affected.
7. ESL yoghurt pasteurization system
*ESL yoghurt pasteurizer used for post pasteurization before filling, it keeps 20 seconds at 75℃, for extending yoghurt shelf time.
Advantages of the yogurt production line:
1.pleasure Buffer tank provides stable feeding into pump, especially for high viscosity yoghurt.
2.Small product pressure drop.
3.Conform EHEDG code, special plate used for high viscosity, big gap 3.96mm/316L, higher hygienic and anti-corrosion grade.
4.Hot Products heat exchanged with cold products, this design reduce public energy markedly, as well as operation cost.
5.Hot water used as heating medium, small temperature difference（△t<3℃）.
6.Products with heating/cooling medium, and products with products has pressure difference design, hot water system、ice water system and product system have independent pressure monitoring system, to ensure pasteurized products pressure higher than no pasteurized products or medium.
7.Product reversed during high temperature stage, this design make sure high viscosity products fully sterilized.
8.Our yogurt production line could be Self-Cleaning.equipped with independent big flow cleaning pump to ensure complete cleaning.
9.All pipe line elbows have big diameter.It reduces pressure and viscosity loss.
The pipe line connected to aseptic tanks equipped with heating and insulation, to ensure low pipe line transporting resistance, and avoid damage to yoghurt viscosity .
Processing of our yogurt production line (single machine introduction)
Milk tank is composed of the food grade stainless steel tank body.the heat preservation layer.Import USA high performance compressor.the agitators.the control panel .storage temperature from 3~6 degrees celsius.tank is controlled by a micro-computer so could be reached the cooling in very short time .The programmed control unit could automatically start and stop when milk reach the set temperature.So could be effectively to preventing the deterioration of the fresh raw milk.The tank thermal insulation layer is filled with polyurethane foam with small thermal conductivity, so it has a lightweight and good thermal insulation effect.
2.Filtration(single filter or double filter)
single filter or double filters are major used to filter impurities in the milk .The impurities may from human hair or cow when milking .The milking will be cleaned with these filters.Double filters should be preferred for machines with large milk output.very good sealing and easy to change filter element .
The Filter milk enters the preheater by a milk pump .Temperature is heated up 40~50 degree in the preheater tank equipment .
The milk homogenizer also called high pressure homogenizer.Homogenization is very important process for milk in the yogurt production line because it’s the quality and taste of milk key factor.the high pressure homogenizer is used for homogenization and emulsification with liquid raw material and density less than 0.2 temperature lower than 80degrees .the principle as follows:the processed milk is sent to the homogeneous valve in the form of high pressure through the reciprocating motion of three pistons so the milk is subjected to the compound force at the moment of flowing through the tiny gap between the disc and the valve seat.The rough milk is processed very fine and the fat particles in the homogenized shrink and completely dispersed in the milk.It is prevents adhesion and coagulation.Also more conducive to human absorption.
5.Sterilization(Sterilization machine) for yogurt production line
In the yogurt production line .Sterilization is a very effective way to extending the shelf life of fresh milk.It is also necessary to make sure that the water level in the sterilizer as same as the water lever on the indicator mirror .The sterilization set temperature usually 85 degrees.Make sure the heating button is activated and the machine will starts work.sterilization .mixes and gives alarm automatically when reach the sterilization temperature.
6.Pre-cooling /pre-cooling machine for yogurt production line.
After sterilization is completed .The milk is pumped into the pre-cooling tank by milk pump and the pre-cooling tank and cooling tank are the same tank.The both process are completed by different temperature .The cooling time is during 0.3~0.5 hours.The temperature of the milk could be lowered below to be 45 ℃.otherwise the shelf life of the milk and service life of the machine will be affected.
once the cooling competed .the tank has the function of the fermentation that’s could be controlled the temperature at about 42 degrees after adding the probiotics.The fermentation was processing for 8 hours.Finally the yogurt is obtained.Above it is the full yogurt production line.
7.Filling and Packing/filling and packing machine for yogurt processing line
In the yogurt production line the packing machine material is food grade 304L or 316L that is automatically drop cup/filling /film release/sealing and cupping etc.The machine have smooth corners not sharpe edges so that avoid skin cuts.the packing machine evenly heated.high temperature resistance. no deformation. can ensure the beauty of the finished products packing. 1100 cups can be filled in 1 hour. This equipment is workable for the packaging of any viscous material.
