Classification of tablet press: Models can be divided into single punch tablet press, rotary tablet press, sub-high speed rotary tablet press, automatic high speed tablet press and rotary core tablet press.
The sheet shape pressed by the tablet press is initially flat circular, and later developed into shallow circular arc and deep circular arc on both sides, which is for the need of coating. With the development of special-shaped tablet press, oval, triangle, oblong, square, diamond, circular ring tablets followed. In addition, with the continuous development of preparations, due to the requirements of compound preparations and timed release preparations, special tablets such as double layer, triple layer and core coating are made, which need to be completed on special tablet press.
Rotary tablet press is a machine which is made of several pairs of die distributed on the turntable to make a circular lifting movement according to a certain track and press the granular material into tablet through the press wheel. And the stamping rod with the rotary table rotating speed ≥60m/min line press is called high-speed rotary tablet press, this high-speed rotary tablet press has a forced feeding mechanism, the machine is controlled by PLC, has the automatic adjustment of pressure, control the weight of the piece, eliminate the waste piece, print data, display fault shutdown and other functions, in addition to the control of the weight difference within a certain range, Quality problems such as missing Angle and loose lobe can be automatically identified and eliminated.
With the development of market demand, the scope of application of tablet press is more and more wide, no longer simply limited to the suppression of Chinese and Western medicine tablets, more widely suppressed health food, veterinary medicine tablets, chemical tablets: such as mothballs, washing blocks, smurf blocks, art powder, pesticide tablets, food tablets: chicken essence block, isatis root block, divine Qu tea block, compressed biscuits.

Everything you need to know about Recumbent Tricycles
In recent years, adult tricycles have gained significant popularity. While most people are familiar with the traditional upright tricycle and may have ridden one as a child, fewer are acquainted with the recumbent tricycle. Even fewer have ever tried one. Despite both being classified as "tricycles," they differ in many ways, offering completely distinct riding experiences.
A recumbent tricycle, often called a recumbent trike, gets its name from the rider's reclined position. The word "recumbent" means "lying down or leaning back," which perfectly describes how the rider sits—more relaxed and supported. Unlike the upright trike, which requires leaning forward, the recumbent design allows for a more comfortable posture with a wider seat and backrest. This makes it ideal for leisurely rides and long-distance travel.
Riding a recumbent trike provides a good workout, but it’s generally less intense than riding a standard bicycle because it doesn’t require the same balance and effort. If your goal is to get the most intense cardio workout, a regular bike might be a better choice. However, for those who value comfort and ease of use, a recumbent trike is an excellent alternative.
Many people choose recumbent tricycles for ergonomic reasons. The weight is distributed over a larger area, reducing pressure on the sitting bones, hands, and feet. This makes it especially beneficial for individuals recovering from injuries, those with physical limitations, or older riders who find upright positions uncomfortable. It also offers increased stability, making it safer for those who struggle with balance or feel uneasy on traditional bikes.
The history of recumbent tricycles dates back to the late 1800s, with early designs appearing in the 1890s. One of the first known models was the “Normal Bicycle†designed by Charles Challand. Later, in the early 1900s, Charles Mochet created the Velocar, a four-wheeled recumbent that laid the foundation for modern designs. Though banned from racing by the Union Cycliste International in 1934, interest in recumbents resurged in the 1970s, thanks in part to innovations like the Ground Hugger by Robert Riley.
Today, there are several types of recumbent tricycles, including Delta, Tadpole, and Tandem models. Each offers unique features, such as different wheel configurations and steering mechanisms. Whether you're looking for speed, comfort, or a way to ride with a partner, there's likely a model that suits your needs.
When choosing a recumbent trike, consider important features like brakes, drivetrains, and cargo options. Disc and drum brakes are common, with disc brakes preferred for their power and reliability, especially on hilly terrain. Drivetrain options include derailleur systems or geared hubs, depending on your preference for maintenance and performance.
Accessories like helmets, lights, bells, and mirrors are essential for safety. A helmet is always necessary, no matter the riding position. Lights help increase visibility, while a bell or horn can alert others to your presence. Mirrors are particularly useful for recumbent riders, as the low seating position can make it harder for drivers to see you.
Finally, don’t forget about insurance. Companies like Velosurance offer coverage for tricycles, providing peace of mind in case of theft, damage, or accidents. Whether you’re commuting, exploring, or simply enjoying the ride, protecting your investment is smart.
If you're considering a recumbent trike, take the time to research and test ride different models. With so many options available, you're sure to find one that fits your lifestyle and preferences.
