50TPD Wheat Flour Mill Machine

This is a 50 tons/day automatic commercial wheat flour milling plant adopting integrated processes of multi-stage cleaning, washing, tempering, second cleaning system,, grouped skin-core separation grinding, purifier,multi-grade sifting, enclosed pneumatic dust removal and automatic quantitative packaging. The whole line is built on an integrated steel frame platform and equipped with a centralized electric control system to realize fully automatic continuous operation. Featuring a precision skin-core separation process, it completely separates bran and endosperm grinding routes, effectively solving the common problems of traditional mixed milling such as excessive bran specks, high ash content and poor flour color. The plant stably produces high-quality refined wheat flour and complete bran flakes, which is ideal for medium and small professional mills, grain processing enterprises and standardized toll processing production.

Raw Material Adaptation

For wheat: optimum moisture 15~16.5%. Soft wheat:14.5~15.5%; hard wheat:15.5~16.5%.

Total impurities: ≤1%. Side-by-side stones, mud lumps and metal debris must be removed. (Destoner and magnetic separator are recommended as supporting equipment). Long straw, hemp rope, plastic scraps and large straw residues are strictly prohibited from feeding, as they are prone to tangling the pneumatic conveying system and rotary sieve.

Core Production Parameters

Daily processing capacity	50 tons of Wheat per 24 hours
Total installed power	167.15 kw
Flour extraction rate	65-80%
Daily flour output	32.5-40 t/d
Working mode	Fully automatic continuous operation

Finished Product Quality Standard

Final flour quality depends on raw grain quality, tempering moisture, sieve mesh and flour extraction rate. Higher extraction rate leads to higher ash content and more bran specks. Lower extraction rate is required for high-purity low-ash flour.

Flour fineness:

90-120 mesh, Moisture: ≤14.5%, good storage performance, not easy to mildew

Ash content (dry basis):

≤1.10 %

Processing Configuration

Cleaning Section

Raw wheat firstly goes into cleaning equipment, where straw, dust, stones, metal fragments and other impurities are removed by sifting, air separation and magnetic separation.

Wheat Washing Section, Tempering Section

Cleaned wheat is delivered to the wheat washer to thoroughly clean stubborn dirt and residual impurities in wheat grooves, complete preliminary moisture adjustment, eliminate mildew odor and improve grain cleanliness. The washed wheat enters the tempering system for constant-temperature conditioning and static treatment, with the milling moisture strictly controlled at 15%–16.5%. This process toughens the wheat bran cortex while keeping the endosperm brittle, enlarging the physical property difference between skin and core, which is the key to accurate skin-core separation. After tempering, grains are finely polished by the iron roller dehairing machine to remove residual wheat hair, floating skin and fine impurities on the surface, further reducing flour ash content and bran specks and significantly upgrading finished flour quality.

Flour Milling and Sifting

The production line is equipped with ten sets of roller mills for coordinated operation, adopting a professionalgraded skin-core separation grinding technology that abandons traditional mixed milling. Based on the physical characteristics of tough bran and brittle endosperm, independent grinding passages are set for skin grinding and core grinding respectively. Mixed materials after grinding are transported to 2 sets of double-bin plansifters for multi-stage precision sifting. Through sieves of different mesh sizes, materials are accurately classified into three types: qualified refined flour, intermediate materials for regrinding and finished bran. Qualified flour is delivered to the finished product conveying system; insufficiently ground intermediate endosperm automatically returns to the roller mills for secondary fine grinding; bran is discharged separately. The closed-loop cyclic processing eliminates raw material waste and guarantees the purity and precision of finished flour.

Package Section

Purified finished flour is automatically conveyed to the 10–25kg automatic quantitative packing scale. The packaging weight can be adjusted freely, and the equipment automatically completes metering, bagging and blanking procedures with high measurement accuracy and high packaging efficiency. It adapts to bulk storage, bagged storage and external sales of finished products, greatly reducing labor costs.

FAQ

Q1: What is the processing capacity of this Wheat flour mill line?

Raw material input: 50 tons of wheat per day.as working 24 hours

Q2: What moisture content is required for raw wheat?

Soft wheat:14.5~15.5%; hard wheat:15.5~16.5%.

Q3: Can we adjust the fineness of final Wheat flour?

Yes. Different replaceable screen meshes can be installed in the sifting machine to change flour fineness, multi-grade products are available.

Q4: What is flour extraction rate and ash content?

For good-quality wheat, total flour extraction rate 65-80%. Dry-base ash content ≤0.85%. Higher flour yield will bring higher ash and more bran specks.

Q5: How many operators are needed?

2-3 workers for feeding, monitoring and finished-product collection. No large labour force required.

Q6: Is installation difficult? Will you supply drawings?

Layout drawing, foundation drawing and pneumatic layout drawing are provided. Customer prepares workshop, foundation, water and power. Remote installation guidance is available. On-site installation service is optional at extra cost.
