Parts and Service
What's the difference between the old Raytek IR sensors and the new Raytek IR sensors?

The new TX series of Raytek sensors does not have external programming boards or the need for special cables. The TX has proven to be far more reliable than the older series Raytek IR sensors.

The TX is stocked, pre-programmed with a standard program used on all Casa Herrera ovens. This minimizes customer down time. The TX can also be custom program to suit your baking requirements.

Retrofit kits are available to upgrade older ovens.

Production
How can we fix too much weight variation of my Corn Tortilla packages?

We all know how important package weights are.  Torilleros must meet specific weight limit guidelines - both under and over - weights or be legally liable.

To keep your weights accurate, you must check a number of variables:

  1. Equipment:  Check the bearings.  If they are worn, this may cause light or heavy weights.  Weigh every other tortilla.  Check oven temperature and make sure it is not over-baking which can result in low moisture and lower weights.
  2. Raw Materials:  Use good corn or flour.  Other operations such as steeping, washing and grinding corn must be standardized to maintain dough consistency and viscosity.
  3. Operator Error:  Yes, this sometimes happens. Set tight weight ranges close to the minimum weight requirements and monitor them closely.

Casa Herrera stands behind all their products.  Contact us if you need one of our professional consultants for any on-site checks and repairs.

Why does my product stick to the belt?

Product sticking can be caused by numerous problems; poor draft, climate change, product moisture change, dirty air filter on the combustion blower are all causes to this problem.

 

Why does my oven backfire?

This may be caused by a leak in the combustion system. Check for holes in manifolds, plumbing and burners. Also check ribbon burners for collapsed ribbon.
