A. VACUUM PUMP
B. MICROFILM COOKER
C. SYRUP PUPA
D. SYRUP TANK
1. … is made of stainless steel construction; the syrup tank is mounted at
the back of the main column, where it is freely accessible.
2. … is a self-contained variable stroke piston type pump, motor driven
through a reduction gear, is provided to draw the syrup direct from the tank
from where it is pumped in a metered flow to the syrup inlet at the top of the
cooking rotor.
3. … consists of a vertical inner cooking tube surrounded by a steam jacket,
capable of operating on a steam pressure of up to 13.6 Atmospheres (200 lbs per sq.
inch). The rotor unit is lagged and encased in a stainless steel cover. Inside the inner
tube a high speed revolving shaft carries a series of high speed centrifugally loaded
spreader blades which wipe the syrup in a very thin film on the inner surface of the
cooking tube due to the rapid movement of the syrup film over the cooking surface.
A very great intensity of heat exchange between the cooking tube and the syrup is
obtained; thus giving a high output of cooked sugar from a very compact unit.
At the base of the rotor, the cooked sugar falls into a stainless steel collecting
chamber, fitted with sight glasses, which is connected to the discharge pump.
4. … has been specially designed for removing high boiled sugar conti-
nuously from the collecting chamber and is dependently motor driven through a
variable speed drive. The outlet of the discharge pump is fitted with a discharge
pipe through which the cooked sugar is delivered at a convenient height.
5. … is connected via the condenser to the top of the microfilm cooking
chamber. It is fitted with an air bleed regulating valve to set the required degree
of vacuum. The pump is independently driven and an automatic valve ensures
that water is fed to the pump immediately.
