PerMix Vertical Paddle Mixer

Introduction

PAM Vertical Paddle Mixers are efficient and versatile blending machines for batch mixing of free-flowing powders, granules and pellets. They have been used widely in food, enzyme, cosmetics, fine chemicals, & pharmaceutical industry.

Our Vertical Paddle Mixers allow the material particles and ingredients to be mixed with minimal mechanical and thermal stress, which makes this type of mixer a good solution for fragile and heat sensitive product.

PerMix PAM Vertical Mixers are designed with a single shaft with only one ribbon,but is able to provide a multi-dimensional movement of the materials. The ribbon inside the mixing vessel moves the materials upward from the bottom to the top,where the materials then drop by gravity into the center. This generates a good counter flow of the product particles.

The ribbon design ensures that the linear speed of the particles are different from here to there,which results in a turbulence flow field. During this continuous operation,material particles and heat are exchanged quickly which leads to a homogeneous product.

A high speed chopper can be mounted to provide intensive mixing and / or lump breaking. This is very useful when liquid is added to the powdery materials and generate lumps.

The PAM mixers have a cylindrical body with conical bottom,but sometimes can be with flat bottom and scrapers to assist the discharge.

A side mounted access door is included for most of the models for inspection and cleaning purpose,and it is designed to be flush-fitting without creating blind areas for mixing and cleaning.At the bottom of the cone,there is a flush-fitting plug valve(manually or pneumaticali operated)for product discharge.

High level of accuracy with minor component ratio to be 1:1,000,000
Gentle mixing for sensitive materials without generation of heat
Chopper to be installed for intensive mixing and lump breaking
Low minimal feeding volume required
Full discharge with minimal residue
Easy to clean in either dry or wet way
High heat transfer rate, ideal for heating or cooling process of the powders

CIP spraying balls
PerMix PAM mixers can be designed for CIP (Clean-in-Place) with spraying balls for both the mixing vessel and the discharge area.
Heating/Cooling jacket
Jacketed vessel for heating/cooling operation by steam, thermal oil, or water. ASME/PED certificate can be optional for high pressure operation.
Vacuum drying & deaerating
PeMix PAM mixers can be designed for vacuum drying & deaerating or for inner pressure working for special applications. See our Vacuum Mixers & Dryers section for more info
Spray nozzle for liquid addition
Liquid can be added into the powder by spray nozzles which is installed on the top of the mixing vessel. The necessary pump and tank can also be provided by PerMix.
Feeding & Discharging
A variety of feeding & discharging methods can be selected by the customers.
Shorter version with flat bottom
PAM mixers can be designed with a flat bottom to reduce the total height, in order to fit in a limited ceiling height. A bottom scraper is mounted to improve the discharge speed and reduce the residues.
Construction material
PerMix can offer mixers with contact part built in Carbon steel, SS304, SS316/316L, Titanium, Duplex SS, Hastelloy, etc. For abrasive materials we offer hardened steel, or the mixing elements to be coated with materials such as Tungsten Carbide.
