Discontinuous sterilisation through strainer basket boiling apparatuses (Kurztechniken
C.)
Description
In terms of the strainer basket boiling apparatus, a rotary cylindrical screen is installed
into a horizontal, heatable apparatus. Through sterilisation, a pulpy mass results, which is
pressed outward through the rotary screen (mesh diameter approx. 15 to 18 mm) into the
boiling item container. Foreign matter is trapped in the interior of the rotary screen and
can be cleared from time to time.
Economics
At a filling of 8 mg, the total sterilisation time is approx. 1.0 to 1.5 h.
Driving force for implementation
Easy implementation at smaller plants.

Discontinuous sterilisation using sieve disk dryer (Kurztechniken C.)
The strainer disk cooker is a horizontally lying stirring implement where jacket and stir-
rers are heated. Here as well, after the sterilisation is finished the pulp mass is pressed
into a cooking material container by an installed strainer or a strainer that rotates along
the stirrer. The working time for the sterilisation process amounts to only about 1 hour,
due to the intensive mixing and the heating of the stirrer. One uses construction sizes of
up to 15 tonnes.
The stirring implements also have a heated stirrer, which actually are the classical dry
melting implements. They serve simultaneously as dryers, and are mainly used in smaller
plants with lower throughputs. The sterilisation and drying time is 3 to 5 h with a charge of
about 1,5 to 10 t.
Driving force for implementation
Easy implementation at smaller plants.
