Mushtaqs Ltd, of Stratford Road, Sparkhill, was preparing products in “disgusting and dirty” conditions, Birmingham Magistrates Court heard.
A judge was told of a string of problems at the venue, which offers sweet and savoury products and had a cafe.
Environmental health officer Rebecca Callender said conditions were “poor” and dirt and debris had built up.
The floor was dirty beneath equipment while there was a build-up of grease on canopies and extraction units in the main production area.
Shelves where food was being stored and prepared were in a deteriorating condition and hand soap dispensers, mop buckets and floor brushes were dirty, the court heard.
The interior of a chiller was dirty with food debris, while lighting in a number of areas was poor.
A cracked and chipped plate was used in the cafe kitchen and storage boxes were damaged in the cake preparation area.
The officer said food, including samosas, was being prepared at the time.
Simon Davis, prosecuting, said council environmental health officers had visited the site in March 2013 and served improvement notices.
But when they returned two months later, Mushtaqs had failed to comply with 17 of 24 hygiene matters.
The company, convicted of seven breaches of food hygiene regulations, was fined £24,000 and was also ordered to pay £7,249 costs.
