Various scenarios and operating procedures for manual tablet presses

A manual tablet press, also known as a manual tablet press or manual drug press, is a device that presses solid medicines or samples by applying pressure manually. It usually consists of a press mold, a press wheel, a hand wheel, a body and an adjusting device. Simple operation, easy maintenance, and a small footprint make manual tablet presses ideal for use in laboratories and small-scale production. Manual tablet presses can be categorized into single punch tablet presses, multi-punch tablet presses, rotary tablet presses and so on according to different structures and functions. Different models are suitable for different scale of production and experimental needs. For example, single punch tablet presses are suitable for sample preparation and small batch production, while multi-punch tablet presses and rotary tablet presses are suitable for scenarios that require continuous production.

 

In the pharmaceutical industry, manual tablet presses are widely used for laboratory research, small batch production and clinical trial sample preparation.

► Laboratory Research
In the drug development stage, researchers often need to prepare large quantities of samples for experiments and analysis. Manual tablet presses are able to fulfill these needs due to their high precision and flexibility. For example, with a manual tablet press, researchers can easily prepare tablets of different thicknesses, hardnesses and shapes for dissolution, stability, bioavailability and other studies.

► Small batch production
For some new or special drugs with small market demand, manual tablet press can efficiently accomplish these small-scale production tasks. It not only avoids the high cost of large-scale production equipment, but also can quickly adjust the production scale according to the actual demand.

► Clinical trial sample preparation
In the clinical trial stage, a large number of tablet samples are usually needed for patient testing. A manual tablet press can quickly and accurately prepare these samples to ensure that the composition, dosage and properties of each tablet are consistent, thus improving the accuracy and reliability of clinical trials.

 

In the food industry, manual tablet presses are also widely used for food sample preparation, quality testing and quality control.

► Food Sample Preparation
In the process of food science research and development, it is often necessary to prepare food samples of various shapes and sizes, such as candies, cookies, nutritional tablets, etc. The manual tablet press can easily press the raw materials into the required shapes and sizes. Manual tablet presses can easily press raw materials into the required shapes and sizes for subsequent testing and analysis.

► Quality testing
The food industry requires high quality in terms of hardness, crispness and texture of the products. With manual tablet presses, food manufacturers can precisely control the pressing conditions of their products to ensure consistent quality from batch to batch. In addition, manual tablet presses can be used to test the mechanical properties of food products, such as compressive strength and flexural strength.

► Quality control
Quality control is critical in the food production process. Manual tablet presses can ensure that each product meets quality standards, thus reducing defective product rates and customer complaints. By adjusting the gap of the press mold and the pressing pressure, manufacturers can accurately control key indicators such as the thickness, weight and hardness of the product.

 

In cosmetic industry, manual tablet press is mainly used for the preparation and testing of solid cosmetic products such as powder, eye shadow, blush and so on.

► Product Preparation
Cosmetic manufacturers usually need to prepare solid cosmetic samples in different shapes and sizes for market research and consumer testing. A manual compactor can press powdered ingredients into the desired shape and size while ensuring product density and uniformity.

► Formulation Testing
During the development of cosmetic formulations, extensive testing and adjustment of different ingredients and ratios is required. Manual tablet presses can quickly prepare samples of different formulations and ratios for sensory evaluation and performance testing.

► Quality control
The quality stability of solid cosmetic products is one of the most important indicators of consumer concern. With a manual tablet press, manufacturers can precisely control the pressing conditions of their products, thus ensuring consistency in quality indicators such as hardness and crispness from batch to batch.

 

Correct use of manual tablet press is the key to ensure product quality and work efficiency. The following is the basic operation procedure of manual tablet press:

◆ Preparation Clean the tablet press to ensure that the body and the press mold are clean and free of impurities. Check the die clearance and pressing pressure to make sure they meet the product requirements. Prepare the required raw materials and molds. ◆ Feeding and pre-pressing Pour appropriate amount of raw material into the press mold to ensure even distribution of raw material. Gently rotate or shake the press wheel to make the raw materials initially compacted. ◆ Formal pressing Rotate or shake the press wheel vigorously until the raw material is completely compacted into the desired shape and size. Observe whether the pressed tablets meet the quality standard, if necessary, adjust the gap of the press mold and pressing pressure.

◆ Discharge and inspection Tap the press mold gently to dislodge the pressed tablets from the mold. Check whether the appearance, weight, hardness and uniformity of tablets meet the requirements. ◆ Cleaning and Maintenance Clean the tablet press and mold to remove residual raw materials and impurities. Apply appropriate amount of lubricating oil to maintain the normal operation of the equipment. Store the tablet press in a dry and ventilated environment to avoid moisture and corrosion.

When using a manual tablet press, you need to pay attention to the following points:

► Safe Operation
When operating a manual tablet press, you need to strictly follow the safety operation procedures to avoid accidents. For example, when changing molds and adjusting pressure, you need to turn off the power and unplug it; when cleaning and maintaining the equipment, you need to avoid using corrosive substances and sharp tools, etc.

► Mold Selection
When choosing a mold, you need to choose the right one according to the shape and size of the tablet. At the same time, it is also necessary to pay attention to the quality and precision of the mold to ensure that the prepared tablets meet the quality requirements.

► Pressure Adjustment
When adjusting the pressure, it should be reasonably adjusted according to the nature of raw materials and the thickness of tablets. Too little pressure may lead to loosening or delamination of tablets; too much pressure may lead to hardness or rupture of tablets. Therefore, it is necessary to be careful when adjusting the pressure and conduct several tests to find the optimal pressure value.

► Equipment Maintenance
During the use of a manual tablet press, the equipment needs to be maintained and serviced on a regular basis. For example, the parts of the equipment need to be cleaned regularly to remove residue and dust; the moving parts of the equipment need to be lubricated regularly to minimize wear and friction; and the electrical and transmission parts of the equipment need to be inspected regularly to ensure proper operation and safety of the equipment.
