Stick Sifting
Stick sifting is a technique used to remove impurities from grain, an important part of the food production process. This method is used to separate the grain from the other materials in the mixture, such as stones, clods, and husks. It is a simple process that can be completed manually or with the use of specialized equipment.
The process starts by pouring the grain and impurities into a sieve or sifter with a fine mesh bottom. This allows the grain to pass through while the other materials are caught in the mesh. The sieve is then slowly shaken to help separate the grain from the other materials.
The next step involves transferring the grain onto a flat sifting table. This table is usually made of hardwood and can be adjusted to different heights. The height of the table can be increased or decreased depending on the size of the grain and the desired results. The grain is then spread evenly across the table, and a long wooden stick is used to comb through the grain and remove any impurities. This process is repeated until all the impurities have been removed from the grain.
The impurities are then discarded and the grain is ready for further processing or storage. Stick sifting can be used for a wide range of grains, including wheat, barley, rye, oats, and rice.
Stick sifting is a simple yet effective way to separate grain from other materials. It is a time-tested method that is still used today to ensure the quality of food. Stick sifting helps to improve the safety of food production and ensures that the grain is free from any impurities.
