Which Plant is Used to Make Biscuits?

Which plant is used to make biscuits? The answer is a set of automated biscuit processing plant. From feeding to packaging, modern biscuit production requires six links: raw material pretreatment, molding, baking, oil spraying, cooling, and packaging.

Taking the hard biscuit plant with a capacity of 200kg/h as an example, its core equipment includes:

• Vertical dough mixer (temperature control ±1℃).
• Three-roller calender (dough thickness error ≤0.2mm).
• 60-meter gas tunnel furnace (four temperature zones with independent temperature control).
• Precise oil spraying system (30% fuel saving).
• 40-meter cooling line (automatic temperature and humidity adjustment).

Main Machines in this Plant to Make Biscuits

• Dough mixer: Mix flour, oil, water and other raw materials into a uniform dough to control gluten formation (soft biscuits need to avoid over-kneading).
• Dough pressing machine: Roll the dough for multiple times (usually 3 times) to make the dough uniform and smooth, suitable for thin slice processing of hard biscuits (such as soda crackers).
• Forming machine: Roller forming machine: suitable for soft biscuits (high-fat dough), one-time embossing forming pattern. The roller cutting forming machine processes hard biscuits by passing them through multiple rollers and molds, and it automatically recycles the waste.
• Tunnel oven: bake biscuits in different temperature zones (preheating, swelling, dehydration, coloring) to ensure consistent color and taste.
• Oil sprayer: spray oil or seasoning liquid on the baked biscuits to enhance flavor and color.
• Spreader: Evenly spread dry seasonings such as salt, sugar, and sesame on the surface of the biscuits after forming.
• Cooling line: Cool the biscuits from above 80°C to below 30°C, solidify the structure and reduce the moisture (target ≤3%).
• Sorting machine: Use differential and star wheel mechanisms to stand the flat biscuits on their sides for easy inspection and packaging.
• Packaging machine: Manually place the arranged biscuits at the feed inlet of the sorting and packaging line, and the sorting machine transports the biscuits to the packaging area. Packaging according to demand.

Which plant is used to make biscuits? For different biscuits, the equipment is also different. The following are common technical solutions for biscuit differentiation.

• Fermented soda biscuits: add a proofing room (temperature and humidity controllable: 38℃/85% RH)
• Soda biscuits rely on a constant temperature fermentation system (38℃/85% RH) and precise punching technology (≥120 holes/piece);
• Sandwich biscuits require a double-station filling machine (error ≤0.3g) and an ultrasonic sealing module (150℃±5℃).
