Margo Pasteurizers and Mixers
Tanks, control panels and installations made by Margo — from a single tank to a complete production line.
Margo Pasteurizers Ready for Shipping
Tanks manufactured for a client — packed and secured, ready for shipping and installation.
Heating, Mixing and Cooling in One Device
A mixer is a device for thermal processing of milk, used in the dairy, food, chemical and pharmaceutical industries — anywhere a product needs to be mixed, heated and cooled. Made of stainless steel, designed to the client’s individual requirements.
Jacket Construction
Agitator and Material
Mixing is carried out by a single rotating agitator — paddle, screw or frame type, selected according to the type and density of the substance. Gearbox and operating speed are set individually.
The device is made of acid-resistant steel, grade 304 or 316, depending on the substance being mixed. The control panel features an electronic thermostat programmed to the client’s needs.
Example Build: Inner Jacket + Heating Jacket
A specific example of the two-jacket variant (tank + heating jacket) — a versatile device for applications where heating, cooling and mixing must take place in a single tank. Made of acid-resistant steel: the tank itself in 304 steel and the heating/cooling jacket in 304 steel.
- Lid tightly bolted on
- Inspection hatch in the lid, also tightly sealed
- Two 1/2" threads and one 1" thread welded into the lid
- Paddle agitator driven by a geared motor
- Heating/cooling water jacket
- Tank head with a drain outlet in the center
- 1" water connection to the jacket at the bottom of the tank
- 1" water outlet at the top of the tank
- Three legs made of acid-resistant steel profiles

Product Safety and Shelf Life
Pasteurization is a heat treatment that inhibits or destroys almost all pathogenic microorganisms while preserving the flavor and nutritional value of the product. The method is named after Louis Pasteur, who developed it. Products are typically heated to 70–100°C. Pasteurization is applied to milk, wine, beer, meat, cold cuts and fruit preserves — then stored in hermetically sealed packaging.
Low-temperature treatment, longer time. Low-Temperature Long-Time method (LTLT).
High temperature, short time (HTST) — faster, with less impact on flavor.
Rules for Correct Pasteurization
Minimum Time-Temperature Combinations
Recommendations of the U.S. Food and Drug Administration (FDA) — temperature and time considered sufficient to destroy pathogenic microorganisms.
| Dairy Product | Method | Temperature | Time |
|---|---|---|---|
| Milk: whole, low-fat, skim | LTLT* | 62.8 °C | 30 min |
| Cream, chocolate milk | LTLT | 65.6 °C | 30 min |
| Ice cream mix | LTLT | 68.3 °C | 30 min |
| Milk: whole, low-fat, skim | HTST** | 71.7 °C | 15 s |
| Cream, chocolate milk | HTST | 74.4 °C | 15 s |
| Ice cream mix | HTST | 79.4 °C | 25 s |
| Milk: whole, low-fat, skim | HTST | 88.3 °C | 1 s |
| Milk: whole, low-fat, skim | HTST | 90 °C | 0.5 s |
| Milk: whole, low-fat, skim | HTST | 94 °C | 0.1 s |
| Milk: whole, low-fat, skim | HTST | 95.5 °C | 0.05 s |
| Milk: whole, low-fat, skim | HTST | 100 °C | 0.01 s |
| All liquid products | U-P**** | 137.8 °C | 2 s |
LTLT* — low temperature, long time (holding method). HTST** — high temperature, short pasteurization time. U-P**** — ultra-pasteurization, heating before or after packaging.
Control Options
The control panel is selected individually to the client’s needs — from simple start/stop setups with analog thermostats, through programmable controllers, to touchscreen panels with full process automation.
