areation with ring jet


AERATION AND DE-AERATION DURING FILLING WITH VERTICAL IMPELLER

reduction of wall friction in the filling channel via minimized aeration by means of ring gap aeration

ring gap aeration prevents, that air is reaching the core of the product

amount of aeration is depending on the filling speed

this results in a clean filling process under high filling pressure and thus in a dense packing

The HAVER ROTO-Packer(Impeller)

The HAVER ROTO-Packer(Pneumatic)


Advantagesof the

HAVER ROTO-Packer


ROTOPACKER 6 RLE

2 x Inline - Packer 3 LEV

Advantages of ROTO-Packer solutionagainst Inline-Packer solution


lower investment and operating costs

less space requirement / building cost

only 1 product feedonly 1 discharge lineonly 1 spillage system

only 1 bag placer oronly 1operator for manual bag application


higher output

no waiting time forbag placing due toconstant turning of packer(automatic / manual placing)

no waiting time for bagdischarge


dust protection ofoperator / bag placer

the operator / bag placerstands outside of the fillingand bag discharge zone


easier to palletizeor load on truck

due to constant bag streamand equal distance betweenthe bags


highest flexibility for truck loading

higher capacity, no waiting timesno reduction during truck change


manual purging

automatic purging 6 RLE

automatic product change

* Depends of the different length of the empty bags

critical product change-contamination not acceptable –

purge: T=23min.Moving of adjustment drives:

Tmax=0,5-3min. *Product change: ca. T=27-29min.

Residue emptying:T=2min. Discharge of

bags:T=1min.

Residue emptying:T=2min

Product change: ca. T= 6-8min.

Moving of adjustment drives:Tmax=0,5-3min. *

Purge incl. Flushing: T=3min.


Expansion

ROTO-Packers can be preparedfor later expansion :

e.g. a ROTO-Packer Type 8(4) RLE is equipped with 4 filling spouts in a first step

easy doubling of capacity while keeping theproduct feed, bag placer, discharge conveyor line...
