Product Description

TECHNICAL OFFER

INTRODUCTION:

Riddhi Mixer Granulator is designed to meet special needs of tablet manufacturing

technology. This is achieved by reducing processing time, more homogenous mixing,

Uniformity of Granule size and above all maintaining improved hygiene compliant to GMP

norm.

DESCRIPTION

Machine will be complete with Mixing Bowl, Mixing Blades, Granulator, Pneumatic

Discharge, Motor, Gear Box, Operating Panel and the Control Panel.

MIXING BOWL:

The Mixing Bowl is cylindrical with a large diameter and flat base. The Top portion of the

bowl is conical in shape to assist circulation of cohesive powders. The Bowl is fabricated

from S.S. 316 Quality Stainless Steel with all internal and external surfaces polished to

mirror finish.

TOP LID

Pneumatically Openable (except RMG 50 & 100LTRS) type lid consists of charging hole,

air filter and special type silicon gasket.

MIXING BLADE

Mixing blade consisting of two Nos. full and two Nos. half blades specially designed for

intense mixing. The angles of the blades are such that half blades lift the material and full

blade pushes the material. Continuous action of this with the different ingredient

immensely mixes thoroughly with homogeneously. Mixing blade assembly is mounted on

main shaft with separate bearing housing which fully eliminate any chance of cross

contamination of product with any lubricants. The upper portion of the housing contains

specially designed Teflon seal along with air purging facility. Lower stage housing contains

bearing alongwith oil seals that make it completely leak proof.

BEARING HOUSING

The bearing housing of the main shaft connected to gearbox by means of heavy-duty chain coupling. Chopper

blade assembly consists of a separate baring housing coupled to motor by means of flexible coupling, with

Teflon impregnated gland packing and air seals.

GRANULATING BLADE

A high speed Granulator is inserted horizontally through the wall of the bowl to assist

blending of powder and to break the lumps of the products in to granules of required sizes.

These lumps are formed while wet mixing.

DISCHARGE VALVE

Machine has a side discharge outlet with pneumatically operated. The discharge valve is

exactly matching the profile of the intervene bowl with perfect sealing arrangement.

Pneumatic cylinder housing is specially designed with swivel type arrangement, which

helps for easy cleaning. Safety interlocks are provided to discharge valve as well as top lid

with limit switches.

MACHINE BASE

Rigid Machine base frame made from M.S. Square pipe is designed to accommodate the

mixing bowl and the control panel. The motor V belt drive and reduction gear are also

housed in the frame. The machine base is totally enclosed and removable flush type S.S

give access to motor gearbox and belt drive inside and machine base. Removable S.S. Cover

finished mirroring finish on all side of the machine base frame. Inside of the M.S. base

frame duly epoxy painted to avoid any rusting. The bottom of the base frame duly covered

with M.S. Sheet. So that any oil or dust from belt should not fall on the floor.

ELECTRIC CONTROL PANEL

MAIN PANEL

All the main Circuit like Switchgears, Relays, and MCBs etc. will be contained in a S.S.

Panel box and kept in Non Flame Proof area.

PROCESS TIMER

SAMS make Process Unit with programmable digital timer, auto mode indicating

lapsed/balance time etc.

OPERATING PANEL

An Operating Panel mounted near the mixing bowl for the easy operation in the case of

NON FLP MOTOR. In FLP only Flame Proof Operating unit provided near the Bowl with

auto manual switch, Emergency stop and push buttons for main motor, chopper motor

Discharge valve open and close, ammeter for main motor and chopper motor.

PNEUMATICS SYSTEMS

The machine is supplied with duly required pneumatic systems of FESTO/CAMOZZI Make.

The customer has to ensure, supply of oil free compressed air, also free from any other

possible impurity, which may contaminate the product. Air filter and Air water separator

are also provided with the machine. Pressure regulator is provided to regulate the desired

air pressure. The systems is suitable to accept an Input air pressure of 7kg/cm2 to be

terminated at " " BSP" terminal. Air lubricator is provided to lubricate solenoid valves and

pneumatic cylinders is incorporated in the system.

PRESSURE SWITCH

A Pressure Switch is incorporated in the Pneumatic circuit to ensure that unless required

minim air pressure is available in the system the machine cannot be started. And once the

machine starts and if drop below pre-set the value the machine stops immediately. In case

the Flame Proof Machine the pressure Switch is fitted in main panel. All M.S. parts will be

cladded with SS 304Q sheet and all SS parts will be polished to smooth surface.

STANDARD PROCESSING DURATION :

Dry Mixing approx 3 - 5 Mins
