Overview of Statistical Process Control (SPC) for the Food Industry

 

Taking place:

Friday, April 21, 2017 - 03:00 PM - 04:00 PM UK Time

This is a 10.00 AM Eastern US Start
 
Presenter:

Frank Schreurs, Sr. Technical Trainer, Training and Education Services, Global Food Division, NSF International
 

Webinar Overview:

Statistical process control (SPC) is a method to improve or achieve quality control in a manufacturing process. Support productivity and quality improvement in your facility by designing and implementing a customized SPC program. This session will provide an overview of the SPC techniques and their application in the food industry, including process variation and how to measure it with SPC, control charts and basic concepts including types and uses. Additionally, this session will cover process capability, linking customer and internal specifications to process variations.

Speaker Frank Schreurs has kindly sent over answers to some of the questions we did not have time to answer.

 

 
Tami
Do you think a level 2 site should be using spc?
SPC could be applied to any food safety measureable you have including CCP's.  Typically the Critical Limit on a CCP is assigned as the upper or lower specification. Control limit on the process should be a lot less than that or you are in danger of not meeting your critical limit, which has major product disposition issues.
 
Carlito
May I know how do you differentiate SQC from SPC?
I assume you mean Statistical Quality Control? In this case, if you are using the process control limits to control the process then they could be considered to be similar in nature.
 
Carlito
Is there any other formula aside from sloven formula could be used to determine the sample size?
If you are trying to determine a sample size to look at your distribution data that 100-300 samples over a reasonable period of time is sufficient.  If you are looking at sample size for sub-grouping than there are a number of variables that need to be taken into consideration.
 
Sabir Gill
whats the minimum number of data points to analyse when determining the distribution?
Minimum number for accuracy would be 100.
 
Gayan
If we have a critical limit (let's say water activity < 0.7), what should be process control limitations?
If you continually monitoring water activity .7 should be the Upper Specification Limit.  Process limits will need to be determined by your results and the Upper Control Limit should be less than .7 or you will be in trouble.
 
Carlito
How about the term Mode and Median are they Measures of Center or Measure of Spread?
Mode and Median are measures of Centre.
 
Muhammad Farhan Karim
what is the good std deviation for process??
The value of standard deviation is relative to the data being analyzed so there is no "good" number.
 
Larbi
what is minimum sample size needed for mean analysis
2
 
Simone Can´t you use your CCPs as control limit?
The Critical Limit of a CCP can be used as a specification limit. Hopefully it will either be higher or lower than the respective upper and lower process control limits.
 
Sabir Gill
What are your top picks for software to use for SPC charts
Choice of SPC software is dependant on a number of factors such as types of users, on-line vs off-line, interaction with other devices.
