Kneaders, also known as dough kneaders or spiral mixers, are industrial baking equipment used to mix and knead dough in large quantities. They are used primarily in commercial and industrial bakeries, as well as other food production facilities that require large volumes of dough.
Kneaders are designed to mix and knead dough using a spiral mixing arm and a rotating bowl. The mixing arm is designed to work the dough by rotating and stretching it in a spiral motion, while the bowl rotates in the opposite direction. This allows the dough to be mixed and kneaded evenly and efficiently, resulting in a consistent and high-quality dough.
Kneaders come in a variety of sizes and capacities, ranging from small tabletop models to large, industrial-sized machines. They are typically made of stainless steel for durability and ease of cleaning and may include features such as variable speed controls and automatic timers to make the dough mixing process more efficient.
Kneaders are commonly used for making a variety of baked goods, including bread, pizza dough, and pastry dough, and are an essential piece of equipment in many commercial and industrial bakeries.
What is the working principle of Kneaders?
The working principle of kneaders is based on a combination of rotating and spiral mixing actions that work the dough to create a consistent and well-mixed product. Here's how it works:
1. Loading: First, the ingredients are loaded into the mixing bowl. This typically includes flour, water, yeast, salt, and any other ingredients needed for the particular recipe.
2. Mixing: Once the ingredients are loaded, the mixing process begins. The spiral mixing arm rotates around the bowl while the bowl itself rotates in the opposite direction. This motion works to combine the ingredients and form a dough.
3. Kneading: As the mixing continues, the spiral arm also works to knead the dough. The twisting motion of the spiral arm helps to stretch and work the gluten in the dough, which gives it its elasticity and structure.
4. Resting: After the dough has been mixed and kneaded, it is typically left to rest in the bowl for a period of time. This allows the dough to relax and the gluten to develop fully.
5. Discharging: Finally, the dough is discharged from the kneader, typically through a chute or conveyor belt. It can then be further processed or shaped into the desired product, such as loaves of bread or pizza dough balls.
Kneaders may also include features such as variable speed controls, automatic timers, and temperature sensors to ensure that the dough is mixed and kneaded to the precise specifications required for the particular recipe.
The major components of kneaders include:
1. Mixing Bowl: The mixing bowl is the main component of the kneader and is typically made of stainless steel for durability and ease of cleaning. It is designed to rotate in the opposite direction to the mixing arm, allowing the dough to be mixed and kneaded evenly.
2. Spiral Mixing Arm: The spiral mixing arm is the component that does the actual mixing and kneading of the dough. It is shaped like a spiral and rotates around the bowl to work the dough in a twisting motion.
3. Motor and Gearbox: The motor and gearbox are responsible for powering the mixing arm and bowl. They are typically located at the base of the kneader and may include variable speed controls and automatic timers to allow for precise control over the mixing process.
4. Safety Guard: A safety guard is typically included to prevent accidental contact with the mixing arm or other moving parts during operation.
5. Control Panel: The control panel is where the operator can adjust the speed and other settings of the kneader. It may include digital displays, push-button controls, and other features to make it easy to operate.
6. Discharge Chute: Once the dough has been mixed and kneaded, it is typically discharged from the kneader through a chute or conveyor belt. The discharge chute may be adjustable to control the size and shape of the dough as it leaves the kneader.
