Application Industry: Traditional Chinese Medicine Formula Granule Dispensing Equipment - Specialized Bag Sealing Machine for TCM Granules

Instrument Model Selected: AI-7248

Introduction to Industry Application:
Traditional Chinese medicine (TCM) formula granule dispensing equipment includes processes such as direct dispensing of medicine into bags, bag making, formulation, sealing, and bag discharge. The specialized bag sealing process for TCM granules requires precise temperature control, with a temperature range of 150-200°C. The stability of the temperature control is extremely critical. If the temperature is too high, the bag seal may deform; if the temperature is too low, the seal will not be tight, potentially causing the medicine to deteriorate.

Problems Solved for Customers:
The customer previously used a temperature controller from a Zhejiang-based brand, which had a large size and a high failure rate. Within just six months, issues such as loss of temperature control occurred, leading to downtime and maintenance of the entire machine and causing significant losses for the customer. After rigorous comparative testing of multiple options, the customer chose Yudian’s AI-7248 temperature controller. This product has a compact design, with a width of only 22.5mm, saving installation space in the customer's equipment. It offers precise and stable temperature control, reducing the customer's after-sales costs. The customer is highly satisfied with the performance of this instrument and has given it excellent reviews.

Specific Field Application Description:
The Yudian AI-7248 temperature controller uses four independent PID control channels, making it suitable for multi-point temperature control applications. In scenarios with multiple temperature control points, a bus-type wiring method can be adopted. Multiple instruments can be connected via a bus, requiring only one power input and one RS485 output, saving terminal wiring. Due to the excellent temperature control stability, minimal temperature drift, and a failure rate of only 0.3%, most of the failures are caused by improper parameter adjustments.

Customer Feedback:
Yudian products deliver stable control with virtually zero faults in field applications.
