In applications where a “wet” washdown is necessary, care should be taken to thoroughly dry the shaft
seal areas before introducing new product. Removal and possible replacement of seal packing may be
necessary, depending upon the extent of the wet washdown. Please refer to paragraphs 4.6 or 4.7.
Quick-Disconnect and Sanitary Construction includes provisions for quickly and easily removing major
components of the feeder for complete and thorough internal and external cleaning, usually for sanitation
purposes. Such feeders may likewise be cleaned with water (hot or cold), with certain units also designed
for sanitation with steam.
Fumigation may be a preferred method of sanitization when frequent cleaning is required, particularly
when complete disassembly of the feeder is not practical.
Exterior surfaces of the feeder may be washed-down with water as well; however, only those units
designed accordingly, or those which include Sanitary Construction, are suitable for heavy water
wash-down of the drive motor.
In all instances, once the cleaning process has been completed, the interior surfaces of the feeder (which
contact product) must be dried thoroughly in order to avoid possible operational difficulties.
6.7 General
Periodic cleaning of the entire feeder is recommended, especially when metering adhesive, cohesive or
hygroscopic products.
7.0 RECOMMENDED SPARE PARTS
Since the Model 105 Series of Volumetric Feeders are basically simple and extremely reliable devices,
Acrison does not recommend that any specific component or components be maintained in a user’s
inventory, except possibly, the Metering Auger (10) when helical in design. However, in more crucial
processes, a user may elect to maintain additional components in inventory. The critical operational
components are as follows:
Item Figure(s) Quantity Description
1 2 and 5 1 Motor
2 2 and 5 1 Gear-reducer
3 2 or 3 and 4 1 Gearbox (complete with seal housing assembly
and all components thereof)
8 2 1 Conditioning Auger
10 2 1 Metering Auger
22 2 or 3 1 “A” Drive Gear
23 2 or 3 1 “A” Driven Gear
24 2 or 3 1 “B” Drive Gear
25 2 or 3 1 “B” Driven Gear
45 or 99 6 and 7 1 Tachometer (optional—used with volumetric feeders
furnished with certain model SCR/DC controllers and
with all Acrison weigh feeders equipped with a variable
speed DC drive)
