Technology and Applications of the Said Butter Packaging Machine

## I. Technological Background and Industry Demand

As an important raw material in the food industry, daily chemical products, and the chemical industry, animal fats and oils see their packaging demand steadily grow along with market expansion. Traditional packaging methods—such as drum packing or pre-made bag packaging—suffer from high costs, inconvenient transportation, and a tendency to contamination. Particularly in scenarios like restaurant chains and food processing, there are increasingly stringent requirements for hygiene standards, packaging efficiency, and cost control. Relying on more than 30 years of experience in the research and development of fluid soft-packaging machinery, Said Technology Development Co., Ltd. has developed a series of fully automated packaging equipment tailored to the characteristics of animal fats and oils, such as beef tallow, thereby filling a domestic technological gap in high-cleanliness, large-capacity soft-packaging solutions.

## II. Analysis of Core Technologies

### 1. Class 100 Cleanroom Environment Control

The Said beef tallow packaging machine is equipped with a top-level Class 100 clean laminar flow purification system. Utilizing high-efficiency filters and a positive-pressure air curtain system, this design ensures that the dust particle concentration in the packaging area meets the Class 100 cleanliness standard. This design effectively prevents microbial contamination of the fat during the filling process, thereby extending the product’s shelf life. It is particularly well-suited for applications with stringent hygiene requirements, such as hot pot bases and baked goods fats.

### 2. Modular Design and Material Adaptation

The equipment’s main body is made of food-grade stainless steel grades 304 and 316, which are corrosion-resistant, easy to clean, and compliant with food-grade safety standards. Core components such as the filling valve and horizontal sealing blade adopt a modular design, allowing for quick replacement to accommodate different packaging sizes (1L–25L) and material viscosities (500–50,000 mPa·s). For instance, when filling chilled, kneaded butter (in a semi-fluid state), the equipment is equipped with a heating jacket and a low-temperature resistance system, ensuring stable filling within a temperature range of 2℃ to 85℃.

### 3. Intelligent Control Systems and Measurement Accuracy

The equipment integrates a PLC programmable logic controller with a human-machine interface touch screen, supporting parameter presets, fault diagnosis, and production data traceability. The metering system employs a high-precision servo motor drive, combined with a mass flow meter and a liquid-level sensor, achieving a filling accuracy of ±0.5% and meeting the requirements of continuous industrial production.

### 4. Sterilization and Cleaning Technologies

The packaging film undergoes surface sterilization using a high-intensity ultraviolet lamp (wavelength 254 nm), achieving a sterilization rate of ≥99.9%. The equipment features an automatic CIP (clean-in-place) circulation system, reducing manual intervention and minimizing the risk of cross-contamination.

## III. Application Scenarios and Industry Value

### 1. Restaurant Chains and Food Processing

In applications such as hot pot bases and baking fats, Said equipment offers full-scale coverage—from small 500g packages to large 25kg bags. For example, after a certain beef tallow manufacturer adopted the SYB-Ⅶ high-capacity packaging machine, its packaging efficiency significantly improved. Moreover, the flexible packaging products are easy to standardize, enabling effective control over raw material quality.

### 2. Daily Chemicals and Chemical Industry领域

The equipment is simultaneously suitable for packaging liquids and viscous materials such as lubricating oils, liquid fertilizers, coatings, sauces, and plant-based protein beverages, making it widely applicable.

### 3. Export Markets and Technological Breakthroughs

Said equipment has been exported to more than 30 countries, including the United States, Malaysia, and Russia. Among these, the high-temperature-resistant packaging machines—designed specifically for tropical climates and capable of withstanding material inlet temperatures up to 85°C—are highly popular in the Southeast Asian market.

## IV. Comparison of Typical Models and Performance

| Model | Package Capacity | Production Speed | Applicable Scenarios

|---------------------|----------------|----------------|------------------------------|

| SYB-ⅢSD-F Model | 0.1L-1L | 60-80 bags/min | Small-package culinary fats and oils |

| SJYB-Ⅶ Type | 3L-12L | 3-8 bags/minute | Medium-sized food processing enterprise |

| SJYB-Ⅷ Model | 10L-25L | 2.5-6 bags/minute | Industrial-grade large-capacity packaging |

Through technological innovation and deep engagement with specific application scenarios, the Said butter packaging machine not only addresses the pain points of traditional packaging methods but also drives the animal fat industry toward greater efficiency, safety, and sustainability. Its technological approach and market practices provide a replicable, industrial-scale solution for the fluid soft-packaging machinery sector.
