material moving downward toward the feed auger. All augers are balanced and checked before leaving
the factory. Care should be taken to be sure that the auger is not bent or dropped during installation,
cleaning or servicing of the packer. The physical characteristics of products are especially important to
consider when two or more products are to be packaged on the same machine. If the physical
characteristics of the products vary greatly, it may be necessary to have a different auger for each
product for best results. There are two different style spouts that packers can be equipped with: Live
spout and a non-influencing spout. The non-influencing style spout assembly consists of a cone and
integral inner spout which is mounted to the auger barrel housing, and an outer spout which is mounted
to the front post. Since the outer spout is mounted on the front post it is not influenced by the material as
it comes thru the inner spout. The cone and inner spout provide a means to move product from the
auger barrel housing section to the bag, while the outer spout is weighing the product as it is being
discharged into the bag without the material touching the scale (outer spout). A flexible seal is provided
as the connection between the inner and outer spouts to accomplish this and this seal prevents product
from getting between the spouts. Note: If material gets between the two spouts it can cause an influence
to the weighing system. A movable tapered sleeve/cone is also provided to seal the valve during the
filling process to minimize dust. Correct adjustment of the tapered sleeve is important. When the bag
seals onto this tapered sleeve, the internal bag sleeve must be approximately 1” back from the mouth, or
bottom edge, of the spout. Feed systems can be manufactured in a wide variety of sizes, types, finishes,
and materials to fit a particular application.
AUGER BARREL HOUSING
The auger barrel housing receives product from the inlet hopper and houses the rear section of the
delivery auger. The auger barrel can be manufactured in a wide variety of finishes and materials to fit
any application.
AUGER SEAL ASSEMBLY
There are two types of auger seal assemblies which are used to prevent the escape of product from the
rear of the auger barrel. The stuffing box type and air seal type. The most commonly used is the stuffing
box type which utilizes compression shoes and either lamb’s wool or Teflon packing material. Teflon
packing is typically used for food grade applications. The stuffing box is efficient, provided the wool or
Teflon packing is clean. Abrasive particles of product under pressure from the packing glands can cause
severe wear to the auger shaft. For this reason it is recommended that the wool or Teflon be inspected
periodically, and replaced if necessary. The air auger seal utilizes air. Air is used between the seals, and
air is injected between the seals into the auger barrel. Since the air cannot escape past the seals, it slowly
bleeds into the auger barrel. This creates a positive pressure into the auger barrel, therefore preventing
the escape of product. (Regulator should be set at 2-3 PSI)
