Premixing

A premix is a mixture of vitamins, trace minerals, medicaments, feed supplements and diluents

4

Objectives

• To deliver the micro ingredients in a manner desired by the consumer

• Mixing ingredients together to result in a homogeneous blend has remained unchanged

• Value added solution for feed with sustainable safety and quality

5

Premix industry is charged with responsibility of manufacturing a high quality premix consistently, efficiently and economically

6

Quality Management In Premixing Production

Improve and sustain the quality premixThree interrelated elements are

(quality design, quality control and quality improvement)

Flow Chart Of Premix Production Process

9

Premix Manufacturing Process Comprises

A. Raw materials

1.Selection and specification

2.Purchase

3.Receipt and storage

4.Sampling and analysis

5.Processing

10

B. Formulation

C. Weighing

D. mixing

E. Packaging

F. Labeling

G.Storage of finished premix

11

A. Raw materials

1.Selection and specificationAmongst vitamins stability formsBioavailability, potency and reactivity of

trace mineralsSpecification should be mention by

AAFCO,AOAC,AFMA,I.P

12

2. Purchase Of Raw Materials

Procured from approved vendersNot receive without certificate of analysis

13

Nutrients And Its Sources

14

3.Receipt And Storage Of Raw Materials

Receiver should have much informationSacked ingredients should check for

identificationComplete detail on stock recordsPrevent development of stacking

resistance (not more than 10 bags to be stored)

15

4. Sampling and Analysis

Followed by quality assurance programme

Sample should be done from bottom, center and top layer of bag

Mix and analyze materials

(Instruments like H.P.L.C,flame photometer and spectrophotometer)

16

5.Processing

Processing include i. Sieving

ii. Milling

17

B.Formulation

Critical in manufacturing premix

Physical,chemical characters and bioavailability of ingredients

18

The Batch Sheet Should Comprise Following Details

Name of the premix Code of premix Production date Batch no. of premix Batch size List of ingredients to be mixed Batch no. of ingredients to be mixed Mixing order of ingredients Actual quantity of ingredients to be taken Mixer name and mixing time Instructions regarding packing and mixing Provision for signatures

19

C. WEIGHING

Difficult to achieving desire nutrients without weighing

Precision in weighing is critical for

(Selenium, where mistakes may even prove toxic )

Assurance in weighing can be achieved by calibrating balances

20

D. MIXING

Heart of any premix-manufacturing unit In order to obtain a homogenous

blend( A. Micro mixing and B. Macro mixing)

Content uniformity of the premix is based on

i. Type of Mixer ii. Mixing Time iii.Mixing order

21

E. Packaging

Provides barrier against light, moisture, oxygen

No chemical interactions with the premix Provides good printing surface Sturdy enough to withstand the transport

pressure

22

F. Labeling

Labeling of premix serves two purposes

1. Provides complete information about the premix

2. Gives an identity to the premix

and helps in differentiating from other premixes

23

A premix label should have following information

Name of the premix Composition Dosage of premix Net weight of premix contained in the package (in kg) Batch number Storage conditions Name and address of the manufacturer with logo Disclaimer note if any

24

G. STORAGE

Following steps are recommended The temperature and humidity of warehouse Keep the area clean Keep the area free from pests and rodents Design the storage areas to facilitate the FIFO

(First in First Out) policy No bag should be stored without any label
