South-Eastern Finland University Rotary Tube Furnace

1. Customer Overview

Customer Name: South-Eastern Finland University of Applied Sciences (Xamk)

Customer Requirements To achieve uniform and controllable high-temperature pyrolysis of biomass and other powder materials at laboratory scale, and precisely regulate key process parameters including temperature, residence time and atmosphere. The research aims to develop high-value-added applications of biochar and provide technical support for circular economy and green transition in Finland and across Europe.

During the research on high-value utilization of biochar, the Xamk research team identified prominent drawbacks of conventional static tube furnaces when processing powdery biomass. Material accumulation leads to uneven heating, low heat transfer efficiency and local overheating, which severely compromise biochar quality stability and restrict process scaling research. Accordingly, the team sought dynamic heat treatment equipment capable of uniform heating for powder materials under controlled atmospheres, to build a critical experimental platform for innovative circular economy research.

2. Equipment Introduction

Equipment Name: Tilting & Rotary Tube Furnace Model: PT-1200TX

Core Advantages

1. Rotatable Furnace Tube Driven by an electric motor, the furnace tube features continuously adjustable rotation speed from 0 to 10 rpm, keeping materials in a continuous tumbling state. The rotating design ensures constant agitation of powdered and granular materials during high-temperature treatment, delivering uniform heating for every particle. It effectively eliminates temperature gradients and local overheating or underheating caused by material accumulation in traditional static tube furnaces.

2. Adjustable Tilting Function The tilting angle is continuously adjustable within 0–30°. Combined with tube rotation, it enables composite movement of tumbling and axial migration for internal materials. Researchers can precisely adjust the angle according to material properties and process requirements to accurately control material residence time in the heating zone.

3. Precise Atmosphere Control System Equipped with 2-channel high-precision mass flow meters controlled via touchscreen, with a flow range of 0–3 SLM per channel and a control accuracy of ±1.5% F.S. Three stainless steel needle valves at the bottom allow manual mixing of two different gases. It supports oxygen-free pyrolysis of biomass under high-purity inert atmosphere, preventing high-temperature combustion and ensuring high quality and consistent performance of biochar products.

4. High-Precision Temperature Control Adopting PID automatic control combined with SCR power regulation, the furnace achieves a temperature control accuracy of ±1℃. It supports 30-segment programmable temperature curves with multi-stage heating, soaking and cooling settings, which can accurately simulate the reaction behaviors of biomass at different temperature stages during pyrolysis.

5. User-Friendly Operation & Flexible Mobility Centralized control via a 7-inch touchscreen enables intuitive and convenient operation. The mobile cabinet design facilitates laboratory layout adjustment and daily equipment maintenance.

Equipment Applications

This tilting & rotary tube furnace is specially engineered for dynamic high-temperature heat treatment of powder materials. It is widely applied in powder metallurgy, ceramics, refractory materials, lithium battery electrode materials, new energy and other fields. It is particularly suitable for biomass pyrolysis, catalyst activation, mineral calcination and carbon material modification research.

Deployed in the BioSampo Laboratory at Xamk Bioeconomy and Circular Economy Research Centre, the equipment works in coordination with slow pyrolysis reactors, micronization equipment, XRD and other analytical instruments, forming a complete research workflow covering raw material treatment, pyrolysis processing and product characterization.

3. Comprehensive Value for Customer Research

1. Improved Experimental Throughput Its single-batch processing capacity fills the gap between micro-scale thermogravimetric analysis (milligram level) and pilot-scale testing (kilogram level). It enables the research team to rapidly screen process parameters under industry-relevant conditions and accelerate the transformation from laboratory exploration to industrial scale-up.

2. Fully Controllable Processes Uniform heating guaranteed by rotary design and ±1℃ high-precision temperature control provide high-quality data support for establishing reliable correlations among process parameters, material microstructure and final performance.

3. Accurate Atmosphere Regulation The dual-channel mass flow meter system enables precise proportioning of gases such as nitrogen and carbon dioxide, meeting research demands for various customized activation atmospheres.

4. Excellent Data Repeatability Stable equipment operation and programmable control ensure high comparability among different batches of experiments, strongly supporting the smooth progress of multiple RDI projects and reliable academic output.

5. Maximized Equipment Utilization Beyond biochar research, the PT-1200TX can be flexibly applied to heat treatment experiments of various powder materials, realizing high comprehensive utilization in laboratory scenarios.

4. Customer Feedback

"One of the core missions of our BioSampo Research Center is to utilize various biomass feedstocks to produce high-quality biochar via pyrolysis, and to subsequently apply this biochar in the development of high value-added products. When processing powdered biomass, traditional static tube furnaces often suffer from material accumulation, which leads to uneven heat transfer and severely compromises the consistency of the resulting biochar's quality. The rotating function of the PT-1200TX rotary tube furnace effectively resolves this issue; the rotation of the furnace tube causes the biomass particles to tumble continuously, ensuring that every single particle is heated uniformly—thereby significantly enhancing the quality stability of the biochar. The 30-segment programmable temperature control profile allows us to precisely regulate the heating rate and holding time during the pyrolysis process. Coupled with the precise regulation of the protective atmosphere via a dual-channel mass flow controller, we are able to systematically investigate how process parameters—such as temperature, residence time, and atmospheric composition—influence the biochar's yield and physicochemical properties. The equipment features an intuitive user interface with centralized touchscreen controls, enabling our researchers to master its operation very quickly. This unit has become an indispensable piece of core equipment within our BioSampo laboratory, providing critical technical support for the successful advancement of several national-level RDI projects, including ARVOHIILI and BiBe."

"In our research on sludge char activation and the application of biochar in construction materials, we impose extremely rigorous requirements on the control of activation temperature and atmosphere. The PT-1200TX rotary tube furnace’s adjustable tilt angle and rotation speed features enable us to precisely control the residence time of materials within the heating zone; furthermore, its dual-channel mass flow controllers facilitate the precise control of N₂ and CO₂ ratios—a capability that is critical for our physical activation studies. Since being put into operation over a year ago, the equipment has maintained exceptional stability, demonstrating high temperature control accuracy and an extremely low failure rate. This unit serves not only our own team but is also made available to other research groups at Xamk, resulting in a very high utilization rate. It is fair to say that the PT-1200TX provides a pivotal experimental platform for our research into the circular economy and green transition."
