Description
Evaporated/condensed milk is a kind of milk product, which is made
of fresh milk or goat milk after disinfection and concentration.
Its characteristic is that it can be stored for a long time.
Fresh milk is usually concentrated by vacuum or other methods to
remove most of the moisture, concentrated to about *5%**0% of the
original volume of dairy products, and then added *0% sucrose
canned. The condensed milk is too sweet and must be diluted with
**8 times more water. But when the sweetness meets the requirement,
the concentration of protein and fat is often reduced by half as
much as that of fresh milk. If water is added to condensed milk,
the concentration of protein and fat is close to that of fresh
milk, then the sugar content will be higher.
Because of the different raw materials and supplementary materials,
the refined milk can be divided into sweetened refined milk, light
refined milk, defatted refined milk, semi-defatted refined milk,
color refined milk, fortified refined milk and processed milk.
China used to produce sweetened whole milk and mild milk. In recent
years, with the development of China's dairy industry, refined milk
has withdrawn from the mass consumption market of dairy products.
However, in order to meet the special requirements of different
consumers on the concentration, flavor and nutrition of fresh milk,
there will still be a certain market for concentrated milk produced
by appropriate concentrating technology.
There are many classifications of refined milk, the main ones are
as follows:
According to whether sugar is added or not, it can be divided into
sugar-added milk (sweet milk) and sugar-free milk (light milk).
According to whether raw milk is degreased or not, it can be
divided into: whole milk, degreased milk and semi-degreased
milk.
According to the types of additives, it can be divided into:
condensed milk, coffee condensed milk, vitamin fortified condensed
milk and infant formula condensed milk which simulates human
milk.
Description
Sweetened Condensed Milk Production line
Condensed milk is essentially evaporated milk with sugar
added. The milk is then canned for consumer consumption and
commercial use in baking, ice cream processing,
and candy manufacture. This product has a shelf life of two
years.
*The milk is flash-heated to about **5°F (*5°C) for several
seconds. It is then piped to the evaporator where the water
removed.
*The milk is then concentrated under vacuum pressure until it
measures between ****0% solid. It now has a syrupy
consistency.
*The milk is cooled and then inoculated with approximately *0%
powdered lactose crystals.
*The milk is then agitated to stimulate crystallization. It is
this sugar that preserves the condensed milk.
*The milk is piped into sterilized cans that are then
vacuum-sealed.
Working Capacity From 5 tons/d up to **0 tons/d
