Cream Separator Operating Manual 50 l/h

After receiving your separator check to insure that all parts are included.

Claims for incompleteness should be made to the supplier, since the manufacturer does not accept claims from individual customers.

Thoroughly study the separator operating manual prior to attempting operation.

Do NOT operate the separator before adding oil. Approximately 2/3 cup of light weight machine oil such as sewing machine oil should be used.

Use only freshly strained milk (either fresh drawn, or milk warmed to 30 – 40 deg. C.) of 3 to 5% fat content.

Run the drum up smoothly, without jerks, increasing gradually to a rotational speed of 65 – 75 rpm.

In order to avoid separator breakdown, do not exceed handle rotational speed of 75 rpm.

Heat the milk path prior to separation by running a liter of water through it that has been heated to 40 – 50 deg. C.

The mounting surface should be flat and level to ensure correct operation of the separator.

Pour milk into the bowl, but do not open the cock until operational rpm’s are achieved (65 – 75rpm). Abruptly opening the cock may result in depressurization of the drum.

Insure the drum is mounted correctly to its spindle prior to operation. Do so by turning the handle clockwise and observe that the drum is spinning correctly. In case of increased whipping of the drum, reinstall it by rotating it by 180 deg relative to the spindle groove.

General

The manual drive cream separator is intended for separation of whole milk into cream and fatfree (skim) milk as well as simultaneous removal of contaminants.

The manufacturer guarantees normal operation of the separator if the requirement of the operating manual are met.

Do not operate the separator without oil in the oil bath. Doing so will result in rapid breakdown of the mechanism.

Do not dry the separator at a temperature exceeding 60 deg C., as this may warp some of the parts.

Improvements to the separator over time may result in receipt of a product that varies slightly from the original picture and description.

SAFETY REQUIREMENTS

Do not operate the separator with an incorrectly installed drum or an insecure mount of the separator.

If abnormal noise or chattering are detected, stop the separator. Investigate and remove the cause of malfunction before returning to operation.

Do not operate the separator with a loose drum nut.

The separator handle should not be turned faster than 75 rpm.

Do not disassemble any part of the separator until the drum fully stops.

Do not attempt to stop drum rotation with your hand or by use of a cloth.

Product Design

The separator is comprised of a drive mechanism, a drum, and receiving and delivery devices. The gear mechanism is mounted to a bracket that is fixed to the frame by three screws.

Turning of the drum is accomplished by a gear drive and spindle, powered by the actuator handle.

the gears are lubricated by oil in the oil bath. The drive coupling is lubricated by oil carried by the gears.

The spindle height is preset at the manufacturing plant by means of washers.

The drum is the major operational element of the separator. It is comprised of a base, a disk holder with a set of disks, a sealing rin, a cover and a locking nut.

OPERATION PROCEDURE

Pour milk into the milk receiver. Use only strained fresh milk (freshly drawn or warmed to 30 – 40 deg C.) of 3 to 5% fat content.

Begin turning the actuator handle, gradually increasing speed to 65 – 75 rpm. The indication of correct handle rotational speed is the appearance of butter in the pocket of the butter indicator.

Open the cock (1 in fig 1) for milk outflow only when operational rpm’s are obtained (65 – 75 rpm).

Cream fat content may be regulated by turning the adjusting screw. To increase fat content turn the screw in 1.5 turns beyond flush with the surface of the separating disk.

To reduce fat content the screw may be turned outward up to 5 rotations. (If this is done, the screw may prohibit the removal of the drum cover (42). It will be necessary to return the screw to the flush position for disassembly and reassembly. Use the hex key provided for screw adjustments.)

Stopping the separator

Turn the actuator handle until cream and skim milk stop flowing.

Without stopping the separator, pass no less than 1 liter of skim milk through the separator to remove cream that may still be in the drum.

If it is necessary to stop the separator during operation, close the cock, and stop turning the actuator handle. After the separator has stopped turning, the vessel and drum may be disassembled cleaned and dried.

When removing the drum the spindle may shift up causing the spindle teeth to separate from the gear. When resuming separation, insure toothing is smooth by turning the drum manually clockwise while regulating the actuator handle.

MAINTENANCE AND SERVICE

Service life and reliability depend on maintaining the separator in accordance with the requirements of the operating manual.

Oil should be changed after the first 40 – 50 hours of operation in order to remove residue from initial break-in.

To remove oil, unfasten the separator from the work table and discharge oil from the cover.

Following the initial break-in period, oil should be changed every six months.

At least every six months the mounting screws should be checked to insure tightness. After tightening it is recommended the hollows above the screw heads be filled with plasticine.

Whenever the separator has been disassembled, care must be taken to insure the rack meshes with the gear.

Upon completing separation, all drum parts and the milk vessel (milk receiver, cock, float chamber, float, cream and skim milk receivers) should be thoroughly washed with hot 2% soda solution, rinsed in clean hot water, and wiped dry with a clean towel.

STORAGE REQUIREMENTS

Store the separator milk vessel at room temperature. At very low temperatures the separator plastic parts get brittle. At high temperatures plastic parts may darken or warp.

The drum parts should be stored in the disassembled state in a clean dry location. Protect all separator parts from mechanical damage. For long periods of storage, drum parts and accessories should be coated with petroleum jelly.
