The production process of the unit

The production process description is as follows:

Paddy used as raw material for production of poha is purchased from nearby food grains markets.

The purchased paddy is cleaned in mega and vibro cleaners to remove the large-sized and small-

sized sand particles which come along with the paddy. The cleaned paddy is then soaked in water for

1 day. The soaked paddy is roasted in rotating tunnel roaster for moisture reduction and to soften it.

The softened paddy is then manually fed into the poha (press) machines where it is flattened and

the husk cover of the paddy is removed by machining. These rice flakes are then cleaned in cleaners

and finally packed and dispatched.

1 INTRODUCTION

1.1 Background and Project objective

Bureau of Energy Efficiency (BEE) is implementing a project titled “Supporting National program on

Energy Efficiency in SMEs for Indore (Food) cluster”. The objective of the project is to provide

impetus to energy efficiency initiatives in micro small and medium enterprises (MSMEs) sector in

Indore and Ujjain food cluster in India.

The objectives of this project are as under:

Identifying energy efficient process and technologies that can be implementable by units in

the Indore food cluster;

Identifying 20 MSME units within the cluster that are willing to implement and demonstrate

the above technologies in their units;

Facilitate Bureau of Energy Efficiency (BEE), New Delhi to sign tri-partite Memorandum of

Understanding (MOUs) with the 20 MSME units of Indore food cluster (that are willing to

implement the energy efficient technologies) and their cluster association

Conduct Baseline Energy Audits in 20 MSME food units of the Indore food cluster who have

signed MOUs with BEE;

Establish baseline energy efficiency scenario for the 20 units against which energy savings

shall be computed post implementation

Facilitate the 20 MSME units to implement the proposed energy efficient technologies in

their units.

Conduct post implementation energy audits in the 20 MSME units to establish the actual

energy savings in those units

Development of technology specific case studies (audio-visual and print) for each technology

(during pre-implementation, implementation and post implementation stages).

1.2 Methodology

1.2.1 Boundary parameters

Following boundary parameters were set for the baseline audit:

Audit covered all the identified energy intensive areas and equipments for which energy

efficiency improvement measures were proposed

All appropriate measuring systems including portable instruments were used

The identified measures normally fall under short, medium and long-term measures

1.2.2 General methodology

Following flow chart illustrates the methodology followed for carrying out the project:




Figure 1 General Methodology

The study was conducted in fallowing stages:

Stage 1: Identification of units and conducting walk through energy audit in 5 units to understand

the process and its energy intensiveness, identification of energy saving technologies, assessment of

the measurement system, proposing energy efficient technologies to BEE and units for acceptance,

Stage 2: Identification of vendors for implementation of energy efficient technologies and facilitate

BEE to sign tripartite MOUs with the units that is willing to implement the EE technology and its

cluster association

Stage 3: Formation of project team for conducting baseline energy audits (DEA) in the units that

have signed MOUs with BEE; and conduct DEA in those units – carry out on-site measurement of

energy parameters, collection of historical energy use data for analysis.

Stage 4: Data analysis, quantification of energy savings (in the processes / equipment) post

measurements, and preparation of baseline energy audit report.

Figure 3: Production flow diagram

2.2.2 Process description

JP Hansraj Poha factory, Ujjain is a poha manufacturing unit. The process description is as follows:

Paddy is used as raw material for production of poha. Raw material is purchased from nearby food-

grain markets. Purchased raw material is conveyed to mega cleaner to remove huge sand particles

which come along with the paddy from fields. After removal of larger-sized sand particles in the

mega cleaner, the smaller-sized sand particles are removed from the paddy in a vibro cleaner. Post

cleaning, the paddy is soaked in water for 24 hours. The soaked paddy is heated in a roaster for

removal of moisture and to soften it. The roasted paddy is transferred manually to the poha

machines where the paddy is flattened and the husk is removed from the softened paddy. Then the

material is processed to the cleaner to produce poha (rice flakes) which is then packed and

dispatched.




3 POST IMPLEMENTATION ENERGY AUDIT OUTCOME AND RESULT

During DEA of the plant, all energy consuming equipments and processes were studied. The analysis

of all major energy consuming equipments and appliances were carried out. Based on the analysis,

Energy Performance Improvement Actions (EPIA) had been identified in which EE motor

replacement was the major one is explain below:

3.1 Installation of IE3 induction motors

3.1.1 Baseline Scenario

During the baseline energy audit, M/s JP Hansraj were using less efficient motors which were

installed when plant commissioned. Now these days it is categorized in inefficient motors due to

enhancement in new technology available in the market.

The international organization which prepares & publishes international standards for all electrical,

electronics & related technologies is known as IEC.

The IEC (International Electrotechnical Commission) publishes IS:12615-2011 which is based on IEC

60034-30 (2008) ) which defines New Efficiency Classification for single speed, three phase,

induction motors.

The IS:12615-2011 covers single speed, three-phase, 50Hz, cage induction motors that:

have rated voltage ≤1000V;

have a rated output 0.37kW ≤ PN ≤ 375kW;

have either 2, 4 or 6 poles;

meet frame size to output relation as stipulated in IS:1231 (for outputs covered by IS:1231);

are rated on the basis of either duty type S1 (continuous duty) or S3 (intermittent periodic

duty) with rated cyclic duration factor of 80% or higher;

are capable of operating direct on-line;

are designed for operation on virtually sinusoidal and balanced voltage conditions as defined

in 7.2.1 of IS/IEC 60034-1;

designed for an ambient temperature not exceeding 40°C and altitude not exceeding

1000m;

have degree of protection IP44 or superior;

have method of cooling IC411 in accordance with IS 6362 / IEC 60034-6;

have service factor not exceeding 1.0.

The Efficiency classes defined are:

IE1 - Standard Efficiency

IE2 - High Efficiency

IE3 - Premium Efficiency




The IS: 12615-2011 also stipulates that for motors to be classified as “Energy Efficient”, these must

meet at least IE2 efficiency values.

Figure 4 New efficiency classes of motors

During DEA of the plant, the recommended EE measures & outcome of the implementation i.e.

energy saving & cost economics analysis (Post implementation) is shown below:




3.2 ENERGY SAVING AND COST ECONOMIC ANALYSIS

During DEA of the plant, all energy consuming equipments and processes were studied. The analysis

of all major energy consuming equipments and appliances were carried out. The energy saving and

cost economic analysis after post implementation audit is discussed below:

3.2.1 EPIA 1: Replacement of poha machine motor with energy efficient

motor

In the material handling section, five numbers of motors were studied during baseline audit, i.e.

Baramb motor, cyclone motor, Poha elevator motor, poha machine motor, Dhaan chalna motor,

Dhaan elevator motor, Poha chalna, khatka motor & FD fan blower. These motors were inefficient

and were consuming higher power. It was proposed to replace these motors with high energy

efficient motors.

The table below summarizes the post implementation energy consumption figures of the unit vis-à-

vis the baseline energy audit data.
