1. Introduction
As people’s awareness of environmental protection continues to improve, degradable and environmentally friendly tableware has received more and more attention. As a new type of environmentally friendly tableware, wheat tableware set has gradually become a new favorite in the market with its natural, degradable, safe and non-toxic characteristics. This article will introduce the factory practices of wheat tableware sets in detail, covering the entire production process from the selection of raw materials to the packaging of finished products, and provide reference for related companies and practitioners.
2. Raw material selection
Wheat straw
The main raw material of wheat tableware set is wheat straw. Selecting high-quality wheat straw is the key to ensuring product quality. Wheat straw without pests, mildew, or pollution should be selected, and the length and thickness of the straw should be uniform.
The collection of wheat straw should be carried out in time after wheat harvest to avoid the straw from being exposed to the air for a long time and being polluted and damaged. The collected straw should be dried to reduce its moisture content to a certain extent for subsequent processing.
Natural adhesive
In order to make wheat straw able to be formed, a certain proportion of natural adhesive needs to be added. Common natural adhesives include starch, lignin, cellulose, etc. These adhesives are environmentally friendly, non-toxic and degradable, and meet the environmental requirements of wheat tableware sets.
When selecting natural adhesives, factors such as their bonding properties, stability and degradability should be considered. At the same time, it should be ensured that the source of the adhesive is reliable and the quality meets the relevant standards.
Food-grade additives
In order to improve the performance and quality of the wheat tableware set, some food-grade additives can be added. For example, waterproofing agents, oil-proof agents, antibacterial agents, etc. can be added to enhance the waterproof, oil-proof and antibacterial properties of the tableware.
When adding food-grade additives, the amount of addition should be strictly controlled to ensure the safety and environmental protection of the product. At the same time, additives that meet relevant national standards should be selected to avoid the use of substances that are harmful to the human body.
3. Production process
Straw crushing
The collected wheat straw is crushed to make it into fine particles. The size of the crushed straw particles should be uniform for subsequent processing.
Straw crushing can be mechanically crushed, such as using crushers, crushers and other equipment. During the crushing process, attention should be paid to controlling the speed and strength of the crushing to avoid excessive crushing of straw particles or excessive dust.
Adhesive preparation
According to the requirements of the product, mix the natural adhesive and an appropriate amount of water together, stir evenly, and prepare an adhesive solution. The concentration of the adhesive solution should be adjusted according to the nature of the straw and the requirements of the product to ensure that the adhesive can fully bond the straw particles.
When preparing the adhesive solution, attention should be paid to controlling the amount and temperature of water to avoid the adhesive solution being too thin or too thick. At the same time, the quality of the adhesive solution should be ensured to be stable, free of impurities and precipitation.
Mixing
Put the crushed wheat straw particles and the prepared adhesive solution into a mixing mixer for sufficient mixing. The mixing time and speed should be adjusted according to the size of the straw particles and the concentration of the adhesive solution to ensure that the straw particles can be evenly wrapped by the adhesive.
During the mixing process, attention should be paid to controlling the intensity and direction of the mixing to avoid the accumulation of straw particles or the formation of dead corners. At the same time, the cleanliness of the mixing mixer should be ensured to avoid the mixing of impurities and pollutants.
Molding and pressing
Put the mixed straw particles and adhesive solution into the molding mold for molding and pressing. The shape and size of the molding mold should be designed and made according to the requirements of the product to ensure that the appearance and size of the product meet the standards.
Molding and pressing can be done by mechanical pressing, such as using presses, hydraulic presses and other equipment. During the pressing process, attention should be paid to controlling the pressure and time to ensure that the straw particles can be tightly combined to form a solid tableware shape.
Drying treatment
The wheat tableware set after molding and pressing needs to be dried to remove the moisture in it and improve the strength and stability of the product. Drying treatment can be done by natural drying or artificial drying.
Natural drying is to place the formed tableware set in a well-ventilated and sunny place to let it dry naturally. Natural drying takes a long time, generally takes several days or even weeks, and is greatly affected by weather conditions.
Artificial drying is to put the formed tableware set into drying equipment, such as ovens, dryers, etc., for heating and drying. Artificial drying takes a short time, generally only a few hours or even tens of minutes, and the drying temperature and humidity can be controlled to ensure the stability of product quality.
Surface treatment
In order to improve the surface finish and waterproof and oil-proof properties of the wheat tableware set, it can be surface treated. Surface treatment can be done by spraying, dipping, brushing, etc., and food-grade additives such as waterproof agents and oil-proof agents can be evenly applied to the surface of the tableware.
When performing surface treatment, attention should be paid to controlling the amount of additives and the uniformity of coating to avoid excessive or insufficient additives, which will affect the performance and quality of the product. At the same time, it should be ensured that the tableware after surface treatment meets the relevant national standards and is safe and non-toxic.
Quality Inspection
After production, the wheat tableware set needs to be inspected for quality to ensure that the quality of the product meets the standards. Quality inspection can include items such as appearance inspection, size measurement, strength test, waterproof and oil-proof performance test, etc.
Appearance inspection mainly checks whether the surface of the tableware is smooth, crack-free, deformed, and free of impurities; size measurement mainly checks whether the length, width, height and other dimensions of the tableware meet the standards; strength test mainly checks whether the compressive strength and bending strength of the tableware meet the requirements; waterproof and oil-proof performance test mainly checks whether the surface of the tableware can effectively prevent water and oil.
Packaging and storage
Wheat tableware sets that pass the quality inspection need to be packaged and stored to ensure the quality and safety of the product. The packaging can be designed and made of materials such as paper boxes, plastic bags, and foam boxes according to the shape and size of the product.
During the packaging process, care should be taken to place the tableware sets neatly to avoid collision and extrusion. At the same time, the product name, specifications, quantity, production date, shelf life and other information should be marked on the packaging so that consumers can understand and use it.
The packaged wheat tableware set should be stored in a dry, ventilated, cool place, avoiding direct sunlight and humid environment. The storage temperature and humidity should meet the requirements of the product to ensure the stable quality of the product.
IV. Production equipment
Straw crusher

The mixing mixer is a device that mixes and stirs the crushed wheat straw particles and the adhesive solution evenly. Common mixing mixers include double-shaft mixers, spiral ribbon mixers, etc. When choosing a mixing mixer, factors such as its mixing efficiency, mixing uniformity, and energy consumption should be considered.
Molding mold
The molding mold is a device that presses the mixed straw particles and adhesive solution into shape. The shape and size of the molding mold should be designed and made according to the requirements of the product. Common molding molds include injection molds, die-casting molds, stamping molds, etc. When selecting a molding mold, factors such as molding accuracy, production efficiency, and service life should be considered.
Drying equipment
