Milk is certainly the most delicate raw food to be treated but even the simple drinking milk may contain different amounts of fat. If we consider the dairy products like butter, soft and hard cheese, cream cheese, yogurt, etc., it is clear how wide is the range of foods related to milk that require special equipments for their processing.

Nowadays, the vegetable milk products are gradually changing the eating habits of many people both for their nutritional values and their greater environmental and energy sustainability.
The separation process and the heat treatment of vegetable and animal milk products therefore require a deep knowledge of the field achieved by Pieralisi Group through years of experience, developing always new solutions to offer to their customers for all applications and process requirements of the milk and dairy industry.

– tallow, vegetable and fish oil – fish industry – cleaning of fish until final delivery to the customer, as well as production of fishmeal and fish oil

Waste water treatment

Fruit processing and juice production

– fruit – apple, pear for getting the juice from the same, where technological wastewater is generated as a by-product

When preparing juices before decanter, fruits or vegetables should be washed first, then depending on the type of fruit to grind and / or prune, preheat the ground mixture and perform enzymatic treatment and then insert it into the decanter and into the separator and then to pasteurization. An example of such a preparation is in the functional diagram below.

Waste water treatment

Wine production

– must and sludge in wine production

Waste water treatment

Processing of chicken meat and making of pate

- chicken oil and protein for pate making

In the meat industry, a specific example in the chicken industry where chickens are first
cooked and, when cooked, they release their fat in the form of a soup and extracting protein and fat from the soup through a separator..

Waste water treatment

Processing of potatoes, slaughterhouse, pig industry

– industrial processing of potatoes (yellow and gray stirk)
– pig industry, livestock slaughterhouses, and treatment of technological waste water

In these plants, the process generally proceeds in such a way that all the above mentioned food products are collected and pre-treated at the receiving points.

Sorting, crushing and heating

Sorting, crushing, heating are performed in the pre-treatment processes of food products

Rough separation

It is done rough separation of the liquid phase from the solid phase


It is done treatment of solid and liquid phases individually

Treatment of technological waste water

The resulting process technological waste water, as well as fruit juices, oil and protein, are finally treated in centrifugal decanter or separator with all accessories that is manufactured by Pieralisi
