About Machinefabriek Het Stempel
Who we are
Het Stempel was founded in 1955 as an Engineering Works. In recent years we have specialized in the manufacture of production machines in stainless steel which are being used around the globe. In addition we also make a wide variety of products in stainless steel and other materials for various clients in various branches of industries. Het Stempel is a production company that is equipped with the latest equipment, where innovation and development are of the highest level. Big enough to tackle the largest project and small enough to provide customized solutions. A small selection of our possibilities: welding, milling, turning, stabbing keyway, sheet metal and rolling.

Parts & Machines
Parts (7)
1 / 7

Scraped Surface Heat Exchanger
DescriptionA scraped surface heat exchanger, also called A-unit, is used for the crystallization of product. In a swept-surface heat exchanger, the outer wall of the unit is cooled by a cooling medium thereby cooling the product to the wall or, if necessary, freezes. The blades on the shaft, which can be obtained in a variety of materials are, scraping the product from the wall.
2 / 7

Crystallizer
DescriptionA Crystallizer can be used in two ways. As a low rotating mixer and as an inverter, where at high rotation water is added to the fat.
Depending on the volume, it varies from 75 millimeter to 150 liters, and the residence time in the crystallizer allows the crystals to grow to the desired size. After that the product can be processed further.
3 / 7

Shell and tube heat exchangers
DescriptionShell and tube heat exchangers are used for the pasteurization of a product. Basically there is a lofator a “heating-“, “holding company” and “cool-” section. In the heating section of the product by means walled piping warmed after which the holding-section, these are insulated pipe is kept hot and can unwind. In the double-walled cooling-section, the product is cooled again in order to be further prepared.
4 / 7

Lab unit - MPU
DescriptionOur Lab Unit – MPU: Micro Processing Unit, is a tailor-made machine for making small samples on lab scale.
The units for preparing the product can be made in any desired design. For example an A-unit with a diameter of 30 mm or a C-unit with a volume of 75 ml.
It is also possible to make the MPU fully automatic or CIP-able
5 / 7

Smelter
DescriptionThis unit, known as Onsmelter processed waste product that is not packaged. The product is melted with this unit, and made ready for reuse in the process. This way you minimize product loss. The smelters are available in any desired volume. Ranging from 3,2m³ to 13m³, but any volume is possible.
6 / 7

Piston Pump
DescriptionOur high pressure piston pump is designed to maintain the product flow through the process equipment. The two embodiments are designed for a capacity of, a small pump to 5500 L / hr, a large pump to 7,000 L / hr.
The pumps with their transmission (with inverter) are mounted on a stainless steel frame which are equipped with shock-absorbers. If desired, additional parts for the pump can be supplied. Such as an inline suction filter, a pressure relief valve and a pressure transmitter.
