The automatic peanut butter filling machine is a special equipment for quantitative filling of highly viscous foods (such as pure peanut butter, granular peanut butter, mixed nut butter, etc.). It has multiple functions such as automatic bottle feeding, stirring and feeding, precise metering, filling and sealing, and is suitable for various packaging forms such as glass bottles, plastic bottles, and metal cans. It can effectively solve the problems of viscous flow, particle blockage, dripping pollution, etc. of peanut butter during the filling process, and improve filling efficiency and finished product quality.

　　1. Core structure and technical features

　　Heating and stirring hopper system: Peanut butter needs to maintain a certain fluidity during the filling process, so the hopper is equipped with heating and stirring functions to prevent oil and sauce separation and material condensation, and improve filling stability.

　　Special high-viscosity filling pump: Mostly use servo piston pumps or screw pumps, which are suitable for sauces with high viscosity and particle characteristics, ensuring smooth, accurate and non-stuck discharge.

　　Multi-head filling system design: 2-6 filling ports are configured according to production capacity requirements, and multiple bottles can be filled simultaneously, greatly improving work efficiency.

　　Drip-proof filling nozzle: pneumatically controlled drip-proof device is used to effectively prevent dripping after filling, keeping the bottle mouth and production line clean.

　　Intelligent human-machine interface (HMI) and PLC control: the operator sets the filling weight, speed, temperature and other parameters through the touch screen, and the system automatically records, alarms and diagnoses faults.

　　Optional capping/film sealing module: equipped with automatic capping machine, aluminum foil sealing machine and other back-end equipment to form a complete filling production line.

　　2. Equipment advantage analysis

　　Precise filling, consistent quality: the filling volume error of each bottle is controlled within ±1% to ensure the consistency of the finished product, avoid waste and customer complaints.

　　High efficiency and labor saving: fully automatic filling process, thousands of bottles can be filled per hour, adapting to the production capacity requirements of medium and large factories and reducing labor costs.

　　Clean and hygienic, in line with food safety standards: the equipment is made of food-grade 304/316 stainless steel and has a CIP (online cleaning) system to avoid bacterial residues and cross contamination.

　　Wide compatibility: It can be applied to different types of sauces such as pure peanut butter, granular peanut butter, nut butter, sesame butter, and packaging containers of various specifications.

　　Easy to operate and maintain: modular design, easy to disassemble and clean, greatly improving equipment stability and maintenance efficiency.

　　As an important supporting equipment for the filling process of viscous food, the automatic peanut butter filling machine is playing an increasingly critical role in the field of sauce food packaging with its high efficiency, stability and intelligence. It not only improves the packaging quality and production efficiency of the product, but also brings substantial advantages to the company in terms of food safety, brand building, cost control, etc.
