Production mashed potato specialties just got better with new Hoegger puree processing & separating technology
Ensuring low operating costs and adding reliable cleaning and a straightforward operation, makes the entire production process even more economical.
For more than 30 years, Hoegger has been supplying primarily the potato industry with separators for gentle separating and puree processing. These are used to produce fresh potato puree from whole potatoes. In addition, it is possible to produce specialities such as croquettes, Duchess potatoes, Pommes Noisette from by-products of French-fried potato production.

Peeled or unpeeled and well cooked potatoes are fed continuously into the separator's feed hopper. The feed container is fitted with a mixing and conveying screw which is designed to ensure that it does not form any deposits and that the "first in – first out" principle is guaranteed.

The newly developed separator head
Consistently good separation is ensured by continuously removing unwanted items from the separating disc using closely-fitting knives, and discharging them via the residue output valve. The residue valve is controlled by the adjustable differential pressure between the pump pressure and the residue pressure so that the pressure in the separating unit is maintained at a constant level.
The separating unit, which is open on one side, is generously dimensioned so that the system pressure can be kept as low as possible which, in combination with the control of throughput, knife head rotation speed and differential pressure, has a very positive effect on the separation process and the product quality.
Operating the unit
The newly developed machine has been designed to ensure that it can be cleaned easily and reliably.
The operating and maintenance costs are low because the construction of the machine is maintenance-friendly and requires only few wear and spare parts. A high yield and the machine safety required by regulations are always ensured thanks to the monitoring of the process parameters and modern safety devices.
The new Hoegger Separator PS2000
When installed in fully automatic production lines, the separator is equipped with the necessary monitoring devices and interfaces.
Cost effectiveness of the process
The process is very cost effective owing to the high quality of the end product, an improved yield, low operating costs and, if applicable, the automation of the system.
The quality of the end product results from the even puree processing and the gentle and precise separation process. The improved yield is due to the good separation, the precise control and the resulting consistency over long production cycles.
The operating costs are comparatively low because there are few wear parts and the machine
The new PS2000 is very suitable for the puree and separating process during the production of fresh potato puree, potato specialties or potato flakes. In addition, there are successful applications for sweet potatoes, processing fruits and vegetables.
Producing mashed potato or potato specialties from fully cooked potatoes or by-products of french fry production such as slivers and nubbins (after cooking)
Producing sweet potato mash from pieces of fully cooked sweet potatoes
Making Applesauce or puree from other fruits or vegetables
