With the accelerating pace of life and increasing awareness of healthy eating, grain bars (also known as energy bars, nutritional bars, or cereal bars) have gained growing popularity among consumers as a convenient, nutritious, and portable snack. For food manufacturers, establishing an automated grain bar production line not only meets market demand but also helps improve product quality and production capacity.
So, what equipment does a complete grain stick production line include? What is its production process? This article will analyze the equipment composition, functional characteristics, working principles, and operating processes of the grain stick production line, helping you scientifically select and plan reasonably.
1、 What is a grain stick production line?
The grain stick production line refers to a complete set of equipment system used to continuously and automatically produce grain stick products by mixing, heating, shaping, cooling, cutting, packaging and other steps of various grain raw materials (such as oats, corn flakes, rice, wheat puffed powder, etc.).
This type of production line generally has the following characteristics:
Highly automated, reducing manual operations
Multi functional combination, adaptable to different formulas
Modular design for easy maintenance and expansion
Food grade material that meets hygiene and safety standards
2、 Detailed explanation of the main equipment composition of the grain stick production line
A standard grain stick production line typically includes the following key equipment:
- Raw material mixer
Function: Mix oats, Rice noodles, syrup, dried fruits, nuts, etc. in proportion to ensure even ingredients.
Features:
Optional vertical, horizontal or planetary mixing forms
Made of food grade stainless steel
Equipped with variable frequency speed regulation and automatic feeding system - Syrup boiling pot
Function: Used to heat sugar, glucose, honey, water, etc. to a liquid state to form syrup, which can be mixed with grains for use
Features:
Double layered jacket structure, heated by water bath or steam
Temperature controllable, automatic stirring, to prevent pot sticking
Equipped with discharge pump, can be connected to the mixing system
- Pre mixed system
Function: Preliminarily pre mix syrup with dry grains for subsequent shaping.
Features:
Mix evenly, control material humidity and viscosity
Can prevent raw materials from clumping or sticking to the wall
Equipped with an automatic spraying system (optional) - Forming machine
Function: Press the mixed materials into uniformly thick “grain slices” or strips through a pressure roller.
Features:
Up and down roller pressing design, adjustable thickness
Automatic thermostat prevents syrup from solidifying
Cooperate with the cooling belt to maintain stable appearance - Cooling conveyor belt
Function: Cool the formed grain strips under low temperature conditions to harden and shape them.
Features:
Usually equipped with a 3-5 meter long conveyor belt
Optional air cooling and compressed air cooling
Mesh belt structure facilitates heat dissipation and cleaning - Cutting machine
Function: Accurately cut the entire grain block into small strips according to the set size, which is the finished grain stick.
Features:
Servo control system, adjustable length
Optional rotating knife, reciprocating cutting knife
High precision and minimal waste - Automatic packaging machine
Function: Automatically package the cut grain bars to prevent deliquescence and facilitate transportation and sales.
Features:
Support pillow packaging or three sided sealing
Cooperate with weighing, coding, and printing systems
Food grade packaging materials have strong compatibility
