High Speed UHT Milk Production Line Large Milk Processing Machine ISO Approve
INTRODUCTION
With a product that can be stored for long periods without spoiling and with no need for refrigeration, there are many advantages for both the producer, the retailer and the consumer.This includes expensive products such as cream, desserts and sauces
In a modern UHT plant (ultra high temperature) the milk is pumped through a closed system. On the way it is preheated, highly heat treated, homogenized, ultra highly heat treated, cooled and packed aseptically .Low acid (pH above 4.5 – for milk more than pH 6.5) liquid products are usually treated at 135–150°C for a few seconds holding, by either indirect heating or direct steam injection or infusion. High acid (pH below 4.5) products such as juice are normally heated at 90–95°C for 15–30 seconds holding
All parts of the system downstream of the actual highly heating section are of aseptic design to eliminate the risk of reinfection, include aseptic packaging in packages protecting the product against light and atmospheric oxygen Ambient storage is normalVarious UHT systems:There are two main types of UHT systems on the market-
In the direct systems the product comes in direct contact with the heating medium, followed by flash cooling in a vacuum vessel and eventually further indirect cooling to packaging temperatureThe direct systems are divided into:Steam injection systems (steam injected into product)
Steam infusion systems (product introduced into a steam-filled vessel). In the indirect systems the heat is transferred from the heating media to the product through a partition (plate or tubular wall)The indirect systems can be based on:
Plate heat exchangers
Tubular heat exchangers
Scraped surface heat exchangers
Furthermore it is possible to combine the heat exchangers in the direct systems according to product and process requirements
RAW MILK PURIFICATION
Filtration and centrifugal purification are 2 main way to purify raw milk. The milk processing equipment applied in this step are milk filter and milk centrifugal clarifier. Currently, most large and middle scale mill plants adopts automatic slag extractor and milk clarifier.
Whole line including:
1. Water treatment section
2. Milk receiving or powder dissolving section
3. Preparation section
4. Pasteurization section
5. Filling and packing section
6. CIP cleaning section
7. Chiller
8. Compressor
9. Steam boiler
10. Cooling room
11. Installation material
PASTEURIZATION
There are 3 main process technology to realize milk pasteurization. LTLT pasteurization are carried out at 62-65℃, where the milk is kept for 30mins. Milk processing equipment for LTLT pasteurization contains plate heat exchanger for heating and cooling, and hot and cold cylinder for sterilization. HTST method are undertaken at the temperature of 72-75℃ for 15s. UHT requires the temperature up to 130-150℃ for 0.5s to 15s, which is realized by plate pasteurization equipment.
