Manufacturing Procedures and Controls (Cold press oil expelling plant )

The system includes reception and storage of raw material, cleaning of seeds by aspirator unitfor air seperation ( cyclones) to remove metal, stones, dust and foreign material able to harm

the equipment and contaminate the product. Seeds, nuts or fruits are ground to a smooth

paste.Subsequently, the paste is made to undergo a malaxation (a kneading technique)

process. is the action of slowly churning or mixing milled seeds, typically for 20 to 40 minutes In

other words, the paste is stirred slowly and this action persuades the oil enclosed by the paste

to clump.Next, the oil is extracted by applying pressure to compel the oil to come out of the

paste with process temperatures not exceed 80 Fahrenheit or 27 Celsius. The pressed oil is

filtered and pumped to settling tanks .Some vacuum filters are used to extract maximum oil

from the sludge. The oil cake is milled into a meal and bagged after it has cooled down and

used as animal feed. The filtered oil is allowed to settle undisturbed in a cabinet at rtp for 10-

17 hours before packaging

1. Plant Balances are calibrated on a daily basis and all utensils are kept clean. One feedstock is

brought into the plant at a time. To avoid any errors or mixups, all containers are labeled and

placed in designated areas in the warehouse. Before withdrawal of the raw material, the

containers are checked by the operator for correctness of label and receiving number. Work is

initiated one batch at a time in the plant following standard operating procedures of weighing and

checking each raw material. Weighed batches are labeled and placed on pallets for further

processing. A logbook is maintained for all batches prepared by Labratory. Each material

weighted out is subtracted from the raw material inventory card. Once a particular lot of raw

material is exhausted the inventory card is forwarded to the Director of Operations for filing.

2. Milling: Equipment used for milling are checked for cleanliness by the supervisor before use.Batches are processed following written manufacturing instructions. Upon completion,

paste/slurry are stored in fiber or plastic drums lined with polyethylene bags, sealed, labeled,

reconciled, and transferred to the staging area for compression or pressing. If a product is to be

reworked because of processing problems, the product is quarantined, appropriate adjustments

are made and records are forwarded to Quality Control . A logbook is maintained for all batches

processed by the milling group.

3. Compression/Extraction: The production supervisor checks the equipment for cleanliness,identifies the product to be processed and then transfers the paste to the designated equipment.

Samples of the product are checked against a retain sample to match specifications as per

master standard. A sample is also sent to Quality Control for testing. If the sample meets

specification, the product is entered in the machine logbook and production commences. Oil is

collected in polyethylene lined boxes, labeled kept in the room until the batch is completed. Upon

completion of extraction, the product is reconciled and transferred to the packaging quarantine

area. Oil is collected in polyethylene line drums and upon completion the batch is reconciled.

Subsequently the oil is decanted and sent to packaging. If a product does not meet specification,

it may be reworked as per set procedures, and batch records are updated to indicate all

adjustments made to the oil and product specification.

4. Packaging: Upon completion of all processing, the product is inspected by Quality Control. Aproduct found to contain minor defects is further inspected before being released for packaging.

Products released by Quality Control are either bulk packaged in polyethylene lined fiber boxes,

and labeled with complete product information, or bottled and labeled as per customer

specification. An expiration date, based on appropriate testing by the customer, is also printed on

the finished product. Inspection and packaging records are maintained and samples are

withdrawn to be retained by Quality Control for at least one year past the expiration date of the

product.

5. Sampling and Inspection: All products are manufactured using Good Manufacturing Practices andare continuously being monitored during processing to ensure product quality and integrity.

Representative samples of 100 units are collected for both the core and the finished product for

Quality Control testing, customer approval and as Reference Samples, a set for each need.

6. Storage of Finished Goods: The product shall be quarantined and stored under controlledtemperature conditions until approval and shipping to the customer.
